HIGH VOLTAGE TEST SERVICES



Advantage: Edison ESI

When it involves high voltage equipment testing you can be assured Edison ESI experience will get the job done right the first time. You will have access to Edison resources for diagnostic evaluation and testing of your systems and equipment.

 Testing Capabilities

Our 72KV, 180 Hz induced voltage test equipment is the largest in the Western United States. With our tunable reactors we can match almost any load and measure RIV and PD with our portable test set.

We perform impulse testing up to 2400KV using a 120 kilojoule impulse test system. We can record the test using either analog or digital recording equipment.


Our 3.75 MVA, 80KV test substation and 72 MVAR capacitance bank are specially designed to test 450MVA capacities to ANSI standards.

Our mobile 640 KVAC resonant test set can be used on-site to provide high potential testing for high voltage bus and switchgear.
