I am interning a a power company and a lineman turned in a sheet the other day on a transformer he was called out on. They replaced it with a 50 KVA and the readings were as follows: X1=182 Amps (Phase to Ground), X3=189 Amps (Phase To Ground). This transformer is a 120/240 single phase transformer. I was a little confused when determining the load. Do you take the voltage as 120 or do you take the voltage as 240, when you get it in the method of data he gave. Technically we had 21.84kW on X1 and 22.68kW on X3, which gives a total of 44.52kW for both legs. At this figure the transformer would only be loaded at 89% right? OR would it be (189 + 182) * 240 = 89.04 kW. Which one is the correct loading on this transformer.
