Electrical engineers explain this transformer concept:

[wetwillabee]

I hooked up a transformer with a 600 delta primary, 480Y secondary. I thought that it was delta-delta so I left off the x0. I read around 236V (line to ground) on x1, x2, and x3. Once I realized and grounded the x0, I properly read 277.

Can you explain to me, with diagrams if possible, why connecting the center point gave me my extra 40 or so volts?

connect x1 to your right nipple, x2 to your left, stick x3 in your ass, and ground X0 to your cock, then tell us what the reading is please.

transformers was a movie brah you can't really make one

+ do your own fucking homework.

 

[Mr.Beverage]

if you werent connected to ground then how were you making a measurement with respect to ground? did you measure line-to-line and convert it? also, was it an open circuit?

 

[wetwillabee]

The can was grounded, but the x0 was not grounded. I measured to the can. I did not measure across lines.

 

[Mr.Beverage]

i dunno man. measure the can with respect to ground. its an open circuit right?

I tried to measure your tippy cup but it spilled

 

[wetwillabee]

Yes, there was no load. It went 600V 40A S5 -> fuseless switch -> transformer -> window washing crane. The crane was off.

what do you do man? i see chime in on alot of technical talk, but haven't read what you do.. seem pretty smart and know alot bout engineering.

you just made my brain shit

In my ignorant youth I decided to build my own power supply for my ZX81 computer.

I took the outputs of a 12.6 V center tapped tranny and used one side for +5V, the other side for -5V, and tried to use the outer leads for +12, all with a common ground.

There are easier ways to build a fuse tester.

Can you show a diagram of your circuit?
