[0002] Insulator withstand voltage testing is a test used to evaluate the electrical strength of insulators (components used in power systems to support conductors and provide insulation) under high voltage. This test is critical to ensuring that insulators can operate safely in power systems; however, there are some potential risks when conducting insulator withstand voltage testing.
[0003] During the withstand voltage test of the pot-type insulator, the insulator is placed on the test bench, then connected to the power cord and powered on for the withstand voltage test.
