Ultra low frequency hipot tester is commonly used for voltage withstand testing of power equipment to verify the insulation performance and reliability of the equipment under high voltage. By applying ultra-low frequency high voltage, it is possible to simulate long-term high voltage states and check the insulation performance of equipment under extreme conditions. This test can ensure that the equipment will not experience insulation breakdown during normal operation and abnormal conditions, and can withstand various voltage shocks during actual operation, thereby ensuring the safe and stable operation of the power system. For high-voltage cables, ultra-low frequency high voltage testing can effectively detect insulation defects and aging of the cables, ensuring their safe and reliable operation.
