High potential testing is commonly conducted to find faults in overhead apparatus, switch gears, bus ducts, interrupters, motors and other components that need insulation reliability testing. This test is straightforward and gives a pass or fail. A high test voltage is applied to the conductor to determine if the insulation can resist the test voltage. A break or contaminant will cause an arc to form and burn the insulation.
