HPS Autotransformers

Three-Phase Autotransformers from 3 kVA to 500 kVA

HPS offers three phase autotransformers that are available for applications where small voltage corrections are necessary in a distribution system. They are frequently used as an economical alternative to three phase general purpose distribution transformers to adjust the supply voltage to match specific load requirements when load isolation from the supply line is not required.

Autotransformers can be used as either a step-up or step-down transformer.
