I want to connect the secondary side of two 120/240V transformers in series to get 480V. The transformers are 10 kVA units (additive polarity). The H1 bushings will be tied to the same primary phase, each with its own fused protection (cutout). H2 bushings will be tied to the system neutral...
If a transformer (three or single phase, pole or pad mount) is only 25, 50 or 75% fully loaded what amount of losses are there compared to a fully loaded transformer?? I'm trying to determine if it is cost effective to change out a transformer that is not fully loaded by comparing the cost of...
Does anyone know how the metering accuracy will change depending on the location of a cable or bus through a CT? I know it is recommended a cable or bus be as closely centered as possible in a CT. Also, the metering accuracy decreases when the cable or bus is not centered. But, I'm looking...
