Inductive withstand voltage test with double frequency should be done to grad insulated transformer
in order to detect its insulated objection.The paper presented several methods to measure the test voltage in the test
analyzed the causation of capacitance-rised voltage on voltage transformer and its effect
explained the duration of withstand voltage test.It is pointed out that the cross-reference results of unloaded withstand voltage test is criterion for a transformer.
