Autotransformer, 30 kVA, Primary 600Y Volt, Secondary 480Y Volt, CU Neutral, NEMA 3R

HPS three phase autotransformers are available for applications where small voltage corrections are necessary in a distribution system. They are frequently used as an economical alternative to general purpose distribution isolation 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
