veer make high voltage tester is connected to the conductor (device under test) and erath terminal should be connected so safety ground (earth gorund). If the insulation between the two is adequate, then the application of a large voltage difference between the two conductor separated by the insultator would result in the flow of a very small current. Although this small current is acceptable, no breakdown of either the air insulation or the solid insulation should take place. It device under test draws more current than per set value then tripping will be occurred and test will be off.in this way we can find problem in the insulation of device under test.
