Home / Single phase / 100 kVA single phase pad mounted transformer
100 kVA single phase pad mounted transformer
Eight to twelve houses, a small apartment building, a fast food unit. About 36 x 38 x 44 inches and 950 lb, carrying 417 amps on the secondary at 240 volts.
Where this rating fits
Often the largest single phase unit a utility will set before moving the job to three phase, because the secondary conductors get expensive past this point.
Common questions
How many amps is a 100 kVA single phase transformer
About 417 amps at 240 volts, and about 833 amps at 120 volts. Single phase current is kVA times 1000 divided by the voltage. There is no square root of three in a single phase calculation, which is the most common mistake people make with this figure.
What are the dimensions of a 100 kVA single phase pad mounted transformer
Around 36 x 38 x 44 inches and about 950 lb. Manufacturers vary, so confirm against the approval drawing before the pad is poured. The pad itself needs to be larger than the cabinet, and clearances in front of the doors are set by the utility.
