Power Transformer Testing

Testing of power transformers is important for the manufacturers and end users. Manufacturers need to be certain their units are meeting the desired specifications, while end users need to perform regular maintenance procedures to detect minor fault symptoms before timely and costly failures occur.

As the leader in the field of high voltage test equipment, HAEFELY HIPOTRONICS offers the most complete line of transformer test equipment on the market. Transformer manufacturers, utility & contract workers, repair companies, and research labs will find all the necessary equipment to satisfy their testing needs. HAEFELY HIPOTRONICS also provides installation, calibration, repair and system upgrade services to keep your test systems performing at the highest level.
