Our Focus Areas

This test involves applying a 60 Hz voltage to various pieces of equipment to levels matching the sample’s rating or a value specified by the test initiator. This test will help assess how the equipment will operate under the applied voltage stress.


  • Power frequency high-voltage sources capable of developing 200 kV indoors, 1,200 kV outdoors, and mobile 500 kV outdoors at a maximum 0.5 Amperes
  • ANSI and IEEE standards testing for aerial devices, non-ceramic insulators, ceramic insulator strings, station breakers, and more
  • Outdoor facilities for design testing of new line hardware up to 765 kV
