CORRECTION - PT should be connected to L1 and L2
This video covers the basics of a Potential (voltage) Transformer and some calculations you would use for revenue metering or simply taking voltage measurements.

I think there's a minor error in the placement of one of the high side legs. Current needs to go from L1 to L2, otherwise there's nothing driving electrons through the transformer.

Definitely. Oops

Please can make a video about potential difference and effect on a circuit..

What is the voltage measured at the secondary of the potential transformers? Where did the 116v come from. You should be explaining this part. How to Calculate ?????

Hey Zack, I'm looking at rule 64- 058 (2) trying to figure out what it means by a transformer with a source on each side. I'm thinking it must mean inverter but I'm not sure

What’s the reading if I connect H1 to L2 and H2 to L1? Will it be a minus number? How can that be in an AC circuit?

H2 should be connected to L2.

Absolutely. Oops

Am I missing something? Did her draw the primary windings both on L1 by accident?

@ZackHartle Жыл бұрын

Yep. Oops.

Quick Question. Would your voltmeter read 464 Volts even though it was only reading 116 Volts.? I understand it uses 120 volts. It seems necessary for the "operator" to know what the voltage of the line actually is without having to do math.
