Theory Question… We were hooking up a Buck-Boost trans on a 208v line 230v load circuit and one of my guys asked a question I couldn’t answer. If alternating current relies on the phases sin wave values alternating, does the length of the conductor changes the voltage difference between conductors? If A phase conductor is 80’ and B conductor 83’, does that difference in length throw off your voltage? We tried a few different cut lengths just to see if there would be a difference, and from what we could tell the answer is no. That’s intriguing; you would figure that it would. If you have 60 cycles per second and you have wire lengths that are different, you would think the voltage would be different. Any thoughts. Also, while testing voltage across the buck-boost, we were getting 230v between phases, however to ground was around 145v...?
