I have a situation where I have a 277 Vac, 20 A load about 750 ft from the source. Due to the voltage drop I would like to us a 480/277 transformer at the source and bump the secondary voltage to approximately 285 Vac to compensate for the voltage drop.
Two problems I have is; that I will need to purchase components (Lighting Panel and Circuit Breakers) rated for the higher voltage and finding an appropriate transformer. If I adjust the primary taps on the transformer I will exceed the rating of the secondary because the source is 480 V. If I use a Buck-Boost Transformer it will have to be at the load, which is not acceptable. Please correct me if I’m wrong.
I would appreciate any information or assistance.
