Frequently Asked Questions

What is an AC withstand voltage test?
Also called a hipot or dielectric withstand test, it applies a specified power-frequency AC voltage across the insulation for a defined duration and checks that no breakdown or excessive leakage occurs. It is a routine, acceptance and preventive maintenance test.
Which equipment can this test set cover?
The set is used for power-frequency withstand testing of transformers, switchgear, cables and insulators. Required output voltage and current capacity depend on the capacitance and insulation level of the test object.
Which standard defines the test procedure?
High-voltage test techniques are defined in IEC 60060 and GB/T 16927. The test voltage level and duration are taken from the relevant product standard for the equipment under test.
