To all the Engineering students in the house what converts 415v from transformer to 240v

To all the Engineering students in the house what converts 415v from transformer to 240v

415 is the line voltage, 240 is a phase voltage.

Usually the output of your transformer is distributed to our homes on poles carry 4 wires. Those wires are:

R - red line
Y - yellow line
B - blue line
N - Neutral (often at the bottom)

The voltage across each of the RYB lines and the Neutral is 240V (also called the phase voltage) while the voltage across each pair, RY, YB, RB is 415V.( called line voltage)

Our regular homes requre just 240v for almost everything we do at home. That is why either RN, YN, BN (single phase) is connected to our homes from the poles.

On the other hand, people that use 3phase machines such as induction machines will require more that 240V to power their devices, hence they need the full 415v (RYB 3phase) to be able to operate these machines.

Engineers in the house, forgive any blunders I have made.

If you don't already have a job or would be interested.

I am interested in offering you a trainer position in a skill acquisition center in Lagos.

Send your resume and contact me on liadiyemi5@gmail.com

Let's discuss further.

Regards.

Why does this thread feel like the 3 of you guys came up with this?

Three of which guys if you are not an electrician pack one side

I need answers to my question

I appreciate your kind gesture sir but I base far from Lagos.

What is the convertion formular

Aboks:

What is the convertion formular

Line voltage/ √3 = phase voltage.
415/√3 = 239.****

emoboy4u:
Line voltage/ √3 = phase voltage.

415/√3 = 239.****

Hello, I'm a student, Civil engineering, ABU, may you please share the source of this your knowledge: whether it be website, textbook publication, etc.
Thanks

How is zaria

How is zaria

All is norm in Zaria.

you guys are probably doing EEEN203. There are lots and lots of books.

1. Just Google
2. Visit Electrical Departmental Library.
3. Google more

How samaru

That was 2016/17 session. Now in 500L. I just need it for personal purpose.
Tharaja is too extensive (very in-depth), therefore bulky indeed!

Been long to go Samaru as a result it the lockdown and the ASUU-FG wahala. Though staying within Zaria metropolitan. All is norm within and around us.
Hopes yours also?

Download theraja online, the one I have on my PC is about 500mb. Though, I collected from someone.
