High Voltage Transformers

A high voltage transformer is a transformer having input our output voltages that are significantly higher than common line voltages. These are designed and tested to a higher dielectric test voltage than the operating voltage it is designed to produce.

High voltage refers not only to high output voltage but to high-voltage isolation and high-voltage rectification as well. High voltage isolation transformers are highly insulated from primary to secondary and secondary to ground. These are used to isolate the high voltage components from the rest of the system. Units in this category can either be single or three-phase and like all of our products, are designed specifically to meet each customer's needs.
