 Science/Technology / Energy Efficiency In Industries, Businesses And Services by TalkElectricNG: 5:46pm On Mar 21, 2018 |
Increased energy efficiency in industries, business, services and the reduction of negative environmental impacts go hand in hand. And the smartest solutions need not have negative impacts on comfort or profits. In energy efficiency consultancy, it is wise to consider the technical, institutional, financial and social aspects of improving energy production, transmission, distribution and use. With so many businesses looking for ways to reduce their energy consumption because of cost, environmental concerns or the need to comply with regulations the opportunities to build businesses that deliver on those needs are large and growing. Analysts expect double-digit growth in this energy-efficiency market over the next few years, with more than 70% from commercial and industrial customers, and the rest from residential. The buildings sector accounts for about 76% of electricity use and 40% of all primary energy use and associated greenhouse gas (GHG) emissions, making it essential to reduce energy consumption in buildings in order to meet national energy and environmental challenges and to reduce costs to building owners and tenants. Opportunities for improved efficiency are enormous. By 2030, building energy use could be cut more than 20% using technologies known to be cost effective today and by more than 35% if research goals are met. Much higher savings are technically possible. Building efficiency must be considered as improving the performance of a complex system designed to provide occupants with a comfortable, safe, and attractive living and work environment. This requires superior architecture and engineering designs, quality construction practices, and intelligent operation of the structures. Increasingly, operations will include integration with sophisticated electric utility grids. The major areas of energy consumption in buildings are heating, ventilation, and air conditioning—35% of total building energy; lighting—11%; major appliances (water heating, refrigerators and freezers, dryers)—18% with the remaining 36% in miscellaneous areas including electronics. In each case there are opportunities both for improving the performance of system components (e.g., improving the efficiency of lighting devices) and improving the way they are controlled as a part of integrated building systems (e.g., sensors that adjust light levels to occupancy and daylight). Saving energy in your business can significantly reduce your operating costs and your impact on the environment. Understanding your energy use and taking steps to become more energy efficient can benefit your business in a range of ways. Saving energy will help your business cut carbon emissions, reduce costs and enhance your image. Energy efficiency and conservation should be a part of your business planning. There are many low-cost steps that businesses can take to start saving energy now, as well as more detailed actions that can happen over time. http://talkelectric.ng/2018/03/21/energy-efficiency-industries-businesses-services/

| Technology Market / Switchgears; An Important Appliances For Electricity Generation by TalkElectricNG: 3:02pm On Mar 20, 2018 |
Switchgears are as important and old as electricity generation. The first models were very primitive, all components were simply fixed to a wall. Later they were mounted on wooden panels. For reasons of fire protection, the wood was replaced by slate or marble. This led to a further improvement, because the switching and measuring devices could be attached to the front, while the wiring was on the back. Switchgear is an important component in the electrical system charged that performs the function of carrying, making or breaking the normal current load. Switchgear are used to de-energise equipment and also to clear faults downstream. This enables reliability of the electricity supply. There are generally different classifications associated with switchgear power systems; current rating, interrupting rating, voltage class, insulation type, interrupting device, operating method, type of current, application and purpose. Additionally, those classifications can be further broken down for added specificity. For example, a voltage classification can be further defined either as low voltage (less than 1,000 volts AC), medium voltage (1,000-35,000 voltage AC) and high voltage (more than 35,000 volts AC). By utilizing these classification and sub-classifications, equipment designers and engineers can ensure that the right equipment is utilized with different switchgear power systems. While classification of switchgear power systems are important, it does not mean that only one classification can be used within a specific system. For example, a single line-up can combine several different types and classifications of switchgear power systems. Additionally, ratings and specifications of switchgear power systems must meet several different standards and requirements, which can include IEEE (Institute of Electrical and Electronics Engineers) and ANSI (American National Standards Institute) within North America and the IEC (International Electrotechnical Commission) standards around the world. A switchgear has two types of components: • Power conducting components, such as switches, circuit breakers, fuses, and lightning arrestors, that conduct or interrupt the flow of electrical power • Control systems such as control panels, current transformers, potential transformers, protective relays, and associated circuitry, that monitor, control, and protect the power conducting components One of the basic functions of switchgear is protection, which is interruption of short-circuit and overload fault currents while maintaining service to unaffected circuits. Switchgear also provides isolation of circuits from power supplies. Switchgear is also used to enhance system availability by allowing more than one source to feed a load. Modern business requirements call for upgraded switchgear that ensures optimum safety, reliable power and continued business operations.

| Celebrities / How Big Is The Internet Of Things, Iot? by TalkElectricNG: 4:53pm On Mar 12, 2018 |
Big and getting bigger; there are already more connected things (Internet of Things) than people in the world. Analyst Gartner calculates that around 8.4 billion IoT devices were in use in 2017, up 31 percent from 2016, and this will likely reach 20.4 billion by 2020. Total spending on IoT endpoints and services will reach almost $2tn in 2017, with two-thirds of those devices found in China, North America and Western Europe, said Gartner. Out of that 8.4 billion devices, more than half will be consumer products like smart TVs and smart speakers. The most-used enterprise IoT devices will be smart electric meters and commercial security cameras, according to Gartner. Read more on http://talkelectric.ng/2018/03/12/big-internet-things-iot/

TalkElectricNG:
[/quote][quote author=TalkElectricNG post=58181689]Has Nepa ever brought light and some appliances in your house got damaged? Has it happened to some one you know. This piece explains in details what power surges which causes it are and how you can prevent them
What are power surges?
Power surges are very brief, usually lasting millionths of a second. They can vary in duration and magnitude, varying from a few hundred volts to several thousand volts.
Power surges damage appliances installed in home hence they can be very harmful. They can result from thunderstorms, intense heat, irregular or erratic power supply and also more importantly unstable distribution. Unstable distribution will increase the chances for surges to occur and the sad part of it is distribution companies can find it difficult to regulate distribution.
No matter where you live, your home experiences power surges. Electrical devices handle specific voltage level for which they are designed. Unfortunately, in cases where these devices are subject to higher voltages than they are designed for, damage will occur. Generally speaking the greater the voltages, and the longer the period over which they occur, the greater the chances damage will most likely occur.
To prevent these surges from occurring and possibly damage things at home, it is up to the ;you the consumer to to this.
Solution
Unplug devices not in use
The simplest and easiest way to deal with power surge problems is to unplug appliances not being used at any particular point in time. Usually in our homes we have the bad habit of leaving plugged in so many devices even though not being used.
There is absolutely no need leaving in power tools, washing machines or microwaves plugged in when we don’t need them. Since the refrigerators are required to always be on, we can do ourselves a lot good by reducing chances of surge occurring through the habit of switching off.
UPGRADE INADEQUATE WIRING
If you have an older home, inadequate wiring could be the cause. Some very old Electrical systems in homes will not handle large-capacity refrigerators, entertainment systems and computer equipment.
Some visible signs of inadequate wiring are frequent blown fuses or tripped circuit breakers, or lights that flicker or dim when the refrigerator or another large appliance kicks on.
Don’t ignore these symptoms – they’re a signal that something is wrong, and the problem may become a fire hazard.
FIX OVER LOADED CIRCUIT
If your home is modern , be careful the electrician you use for your house wiring ,you may have a problem with an overloaded circuit. Look out for two (or more) large appliances drawing power from the same circuit, especially in the kitchen. The easier way is to have a single circuit for each appliance if possible.
Another trouble spot might be a circuit with many smaller devices, such as a family room filled with computer and entertainment equipment.
Tell your electrician to establish dedicated circuits for each large appliance, and to divide rooms with multiple devices into separate circuits.

TalkElectricNG:
[/quote][quote author=TalkElectricNG post=57677863]Clean energy will replace fossil fuel in the near future. It existed years back and today is continually improved upon.
In a sense, the fossil fuels are a onetime gift that lifted us up from subsistence agriculture and eventually should lead us to a future based on renewable resources and clean energy.
— Kenneth Deffeyes
The fuel in the earth will be exhausted in a thousand or more years, and its mineral wealth, but man will find substitutes for these in the winds, the waves, the sun's heat, and so forth. (1916)
— John Burroughs
"By definition we must move towards renewable energy. How can people argue against that? To argue that is to say that eventually we will run out of energy and die or civilization will collapse."
—Elon Musk
The amount of energy the sun generates is enough to power the whole world on a 24 hr basis but harnessing this energy in the most efficient way is the task scientists are to undertake. Lately a lot of incredible innovations on clean energy are going on. TalkElectricng will like to share some of them with our esteemed readers.
Tesla roof tiles
Residential solar roof tops have been in existence for so many years and still hold a large chunk of the market space in terms of clean energy power generation. However they have their drawbacks. A couple of home owners complain about how they spoil the design architecture and aesthetics of their houses. Notwithstanding the fact that solar roof top over the years have dropped in prices and provided good Return on Investment, Mr Elon Musk had a proposition.
With the question "Would you like a roof that looks better than a normal roof, lasts twice as long, costs less and by the way generates electricity?' It's like, why would you get anything else?" The founder of Solar city and Tesla battery came up with a game changing idea-Solar roof tiles.
The roof tile technology made from glass and solar cells is unique. The solar cells are embedded in the tiles. Panasonic makes a very robust solar cell that generates power for up to 30 years. What the company has kept a little bit of a secret is the inter connection technology of the tiles.
Elon Musk once said that the electric architecture of the solar roof system was proprietary to Tesla and they didn’t want to go into details about it, but they did briefly discuss the development of the system
The clean energy enterpreneur said that making the connectors robust involved “a shocking amount of technology”:
“This is a connector that has to last for more than 30 years. It has to be weatherproof, heavy rain, snow, slush, salt, water leaking – it’s like connector hell.”
The roof tile went on sale in America on the 10th of May 2017. Tesla opened up its online store and is taking US$1,000 deposits for two of four options unveiled in October: a smooth black glass; and textured-glass roof tiles. From most viewing angles, the slick shingles look like standard roof materials, but they allow light to pass through from above onto a solar cell embedded beneath the tempered surface. The first installations began in the United States in June. However orders from all over the world began too for 2018 installations
For more questions on how these roof tiles work you can visit Tesla or Solar City websites or you can read more about it here.
Solar paint
Researchers have developed a solar paint that can absorb water vapor and split it to generate hydrogen – the cleanest source of energy.
A silica gel like compound makes up the paint component. Works also as moisture absorbent and keeps food ,medicine and electronics dry
But unlike silica gel, the new material, synthetic molybdenum-sulphide, also acts as a semi-conductor and catalyses the splitting of water atoms into hydrogen and oxygen.
Lead researcher Dr. Torben Daeneke, from RMIT University in Melbourne, Australia, said: “We found that mixing the compound with titanium oxide particles leads to a sunlight-absorbing paint that produces hydrogen fuel from solar energy and moist air.
“Titanium oxide is the white pigment that is already commonly used in wall paint, meaning that the simple addition of the new material can convert a brick wall into energy harvesting and fuel production real estate.
“Our new development has a big range of advantages,” he said. “There’s no need for clean or filtered water to feed the system. Any place that has water vapor in the air, even remote areas far from water, can produce fuel.”
His colleague, Professor Kourosh Kalantar-zadeh, said hydrogen was the cleanest source of energy and could be used in fuel cells as well as conventional combustion engines as an alternative to fossil fuels.
“This system can also be used in very dry but hot climates near oceans. The sea water is evaporated by the hot sunlight and the vapour can then be absorbed to produce fuel.
“This is an extraordinary concept – making fuel from the sun and water vapor in the air.”
Actuators
They work by translating the revolutionary motion of a motor into linear movement. Actuators enjoy a long life, and generally do not require maintenance as they have few moving parts. So using actuators is another way in which solar energy is more efficient because it allows freestanding panels to track the sun as it moves across the sky to maximize solar gain.
Energy storage
To date, one of the biggest impediments for solar energy is that the sun doesn't always shine. Large-scale energy storage is gaining traction by the day. It means that towns and cities can store solar gain during the day for use at night. And some of the ideas for solar storage are pretty innovative!
Compressed air: Using abandoned mine shafts or salt caverns to pump gas into during daylight hours. Use the compressed air at night to drive turbines and generates energy.
Pumped Hydro: Another way to store energy is to pump water uphill into a large storage reservoir during the day. Release the water at night to flow downhill where it drives turbines.
Molten Salt: Grid production of excess required energy led to innovation. Heat molten salt to temperatures in excess of 1,000 degrees Fahrenheit from excess energy. The heat from the molten salt creates steam which drives turbines and generates energy in increased electricity demand.

“This system can also be used in very dry but hot climates near oceans. The sea water is evaporated by the hot sunlight and the vapour can then be absorbed to produce fuel.
“This is an extraordinary concept – making fuel from the sun and water vapor in the air.”
Actuators
They work by translating the revolutionary motion of a motor into linear movement. Actuators enjoy a long life, and generally do not require maintenance as they have few moving parts. So using actuators is another way in which solar energy is more efficient because it allows freestanding panels to track the sun as it moves across the sky to maximize solar gain.
Energy storage
To date, one of the biggest impediments for solar energy is that the sun doesn't always shine. Large-scale energy storage is gaining traction by the day. It means that towns and cities can store solar gain during the day for use at night. And some of the ideas for solar storage are pretty innovative!
Compressed air: Using abandoned mine shafts or salt caverns to pump gas into during daylight hours. Use the compressed air at night to drive turbines and generates energy.
Pumped Hydro: Another way to store energy is to pump water uphill into a large storage reservoir during the day. Release the water at night to flow downhill where it drives turbines.
Molten Salt: Grid production of excess required energy led to innovation. Heat molten salt to temperatures in excess of 1,000 degrees Fahrenheit from excess energy. The heat from the molten salt creates steam which drives turbines and generates energy in increased electricity demand.

[/quote][quote author=TalkElectricNG post=58410500]Flood has taken over most homes in Lagos especially the Lekki – Ajah axis and is recently creeping into Abuja. This is not good news for electrical safety in homes. For those whose house have been severely damaged by flood water recently, here are a few tips for electrical safety.
Get back the Professionals
It is best to neutralize the change over between ‘NEPA’ and Generator so that power is disconnected but this is not enough. Available utility power from your Disco will take power up to the meter in the house. Disconnect your meter so power entirely does not get to the building at all. Get in the professionals after the storm to suck out all the water in your basement. Allow it dry then access the electrical damage to your appliances before turning back power on.
Flood Water and Electricity don’t Mix
Water and electricity don’t mix. The flood probably filled up your basement up to the point where your electrical gadgets are submerged fully or partially. Chances are these gadgets will go bad. Nonetheless take an inventory of all your electrical appliances and cables with the help your your professional. They include but not limited to
Plastic-sheathed building wire.
Armored cable for big Generators most especially.
Circuit panels and circuit breakers
Fuse boxes and fuses
Switched disconnect boxes
Switches
Motors
Circuit boards
Non-submersible pumps
Blowers and fans
Lights
Heaters
Air conditioners
Boilers and water heaters
One may tend to just turn back on most of these appliances after the flood dried up. Some appliances go on to live a post flood life, however it is risky. There is high risk of operation involved using them after the flood. Let a professional advise you to keep or replace them.
Mind the Ground
All electrical home systems ideally have two electrical parts for current conduction. The part that conducts current during normal operation within the electrical appliances loop. This has already been addressed. The other part is the one that carry electrical current to the ground during an abnormal occurrence in electricity. This one is called the grounding and bonding system. They severely get damaged more often by flood water. Let your professional evaluate them and be sure they are still good. He should also check back after some weeks to be sure no metallic material needed for grounding rusted. A rust on them prevents proper grounding of faulty current to earth.

TalkElectricNG:
Has Nepa ever brought light and some appliances in your house got damaged? Has it happened to some one you know. This pieace explains in details what power surges which causes it are and how you can prevent them
What are power surges?
Power surges are very brief, usually lasting millionths of a second. They can vary in duration and magnitude, varying from a few hundred volts to several thousand volts.
Power surges damage appliances installed in home hence they can be very harmful. They can result from thunderstorms, intense heat, irregular or erratic power supply and also more importantly unstable distribution. Unstable distribution will increase the chances for surges to occur and the sad part of it is distribution companies can find it difficult to regulate distribution.
No matter where you live, your home experiences power surges. Electrical devices handle specific voltage level for which they are designed. Unfortunately, in cases where these devices are subject to higher voltages than they are designed for, damage will occur. Generally speaking the greater the voltages, and the longer the period over which they occur, the greater the chances damage will most likely occur.
To prevent these surges from occurring and possibly damage things at home, it is up to the ;you the consumer to to this.
Solution
Unplug devices not in use
The simplest and easiest way to deal with power surge problems is to unplug appliances not being used at any particular point in time. Usually in our homes we have the bad habit of leaving plugged in so many devices even though not being used.
There is absolutely no need leaving in power tools, washing machines or microwaves plugged in when we don’t need them. Since the refrigerators are required to always be on, we can do ourselves a lot good by reducing chances of surge occurring through the habit of switching off.
UPGRADE INADEQUATE WIRING
If you have an older home, inadequate wiring could be the cause. Some very old Electrical systems in homes will not handle large-capacity refrigerators, entertainment systems and computer equipment.
Some visible signs of inadequate wiring are frequent blown fuses or tripped circuit breakers, or lights that flicker or dim when the refrigerator or another large appliance kicks on.
Don’t ignore these symptoms – they’re a signal that something is wrong, and the problem may become a fire hazard.
FIX OVER LOADED CIRCUIT
If your home is modern , be careful the electrician you use for your house wiring ,you may have a problem with an overloaded circuit. Look out for two (or more) large appliances drawing power from the same circuit, especially in the kitchen. The easier way is to have a single circuit for each appliance if possible.
Another trouble spot might be a circuit with many smaller devices, such as a family room filled with computer and entertainment equipment.
Tell your electrician to establish dedicated circuits for each large appliance, and to divide rooms with multiple devices into separate circuits.

Good one op. I just notice that just of recent my ftidge stated to shock which never happen before. Now my laptop also shocks not until i brought it to my office and to my surprise it didnt shock at all. not only that my bulp burns regularly and frequently now. sir could it be the power surge you re talking about and how do i correct it. Thought the house is old.
Thank you. There is a wrong connection somewhere. Is it all the sockets that do it? is the fridge and freezer powered from one socket source? Possible the socket is faulty. Also ask an electrician to confirm if the earthing of your house is still functional. It can be corrected. Good luck with that |

Flood has taken over most homes in Lagos especially the Lekki – Ajah axis and is recently creeping into Abuja. This is not good news for electrical safety in homes. For those whose house have been severely damaged by flood water recently, here are a few tips for electrical safety.
Get back the Professionals
It is best to neutralize the change over between ‘NEPA’ and Generator so that power is disconnected but this is not enough. Available utility power from your Disco will take power up to the meter in the house. Disconnect your meter so power entirely does not get to the building at all. Get in the professionals after the storm to suck out all the water in your basement. Allow it dry then access the electrical damage to your appliances before turning back power on.
Flood Water and Electricity don’t Mix
Water and electricity don’t mix. The flood probably filled up your basement up to the point where your electrical gadgets are submerged fully or partially. Chances are these gadgets will go bad. Nonetheless take an inventory of all your electrical appliances and cables with the help your your professional. They include but not limited to
Plastic-sheathed building wire.
Armored cable for big Generators most especially.
Circuit panels and circuit breakers
Fuse boxes and fuses
Switched disconnect boxes
Switches
Motors
Circuit boards
Non-submersible pumps
Blowers and fans
Lights
Heaters
Air conditioners
Boilers and water heaters
One may tend to just turn back on most of these appliances after the flood dried up. Some appliances go on to live a post flood life, however it is risky. There is high risk of operation involved using them after the flood. Let a professional advise you to keep or replace them.
Mind the Ground
All electrical home systems ideally have two electrical parts for current conduction. The part that conducts current during normal operation within the electrical appliances loop. This has already been addressed. The other part is the one that carry electrical current to the ground during an abnormal occurrence in electricity. This one is called the grounding and bonding system. They severely get damaged more often by flood water. Let your professional evaluate them and be sure they are still good. He should also check back after some weeks to be sure no metallic material needed for grounding rusted. A rust on them prevents proper grounding of faulty current to earth.

Has Nepa ever brought light and some appliances in your house got damaged? Has it happened to some one you know. This piece explains in details what power surges which causes it are and how you can prevent them
What are power surges?
Power surges are very brief, usually lasting millionths of a second. They can vary in duration and magnitude, varying from a few hundred volts to several thousand volts.
Power surges damage appliances installed in home hence they can be very harmful. They can result from thunderstorms, intense heat, irregular or erratic power supply and also more importantly unstable distribution. Unstable distribution will increase the chances for surges to occur and the sad part of it is distribution companies can find it difficult to regulate distribution.
No matter where you live, your home experiences power surges. Electrical devices handle specific voltage level for which they are designed. Unfortunately, in cases where these devices are subject to higher voltages than they are designed for, damage will occur. Generally speaking the greater the voltages, and the longer the period over which they occur, the greater the chances damage will most likely occur.
To prevent these surges from occurring and possibly damage things at home, it is up to the ;you the consumer to to this.
Solution
Unplug devices not in use
The simplest and easiest way to deal with power surge problems is to unplug appliances not being used at any particular point in time. Usually in our homes we have the bad habit of leaving plugged in so many devices even though not being used.
There is absolutely no need leaving in power tools, washing machines or microwaves plugged in when we don’t need them. Since the refrigerators are required to always be on, we can do ourselves a lot good by reducing chances of surge occurring through the habit of switching off.
UPGRADE INADEQUATE WIRING
If you have an older home, inadequate wiring could be the cause. Some very old Electrical systems in homes will not handle large-capacity refrigerators, entertainment systems and computer equipment.
Some visible signs of inadequate wiring are frequent blown fuses or tripped circuit breakers, or lights that flicker or dim when the refrigerator or another large appliance kicks on.
Don’t ignore these symptoms – they’re a signal that something is wrong, and the problem may become a fire hazard.
FIX OVER LOADED CIRCUIT
If your home is modern , be careful the electrician you use for your house wiring ,you may have a problem with an overloaded circuit. Look out for two (or more) large appliances drawing power from the same circuit, especially in the kitchen. The easier way is to have a single circuit for each appliance if possible.
Another trouble spot might be a circuit with many smaller devices, such as a family room filled with computer and entertainment equipment.
Tell your electrician to establish dedicated circuits for each large appliance, and to divide rooms with multiple devices into separate circuits.
