[Answer] What Is the Significance of Power-Frequency High-Voltage Testing?

You are probably referring to the power-frequency withstand voltage test.

Power-frequency withstand voltage test equipment is one of the basic testing tools used by a wide range of users, including power stations, power supply and distribution systems, and research institutions. It is used to carry out insulation strength tests on various electrical products, electrical components, and insulating materials under a specified voltage, in order to evaluate a product’s insulation level, detect insulation defects in the test specimen, and measure its ability to withstand overvoltage.

Simply put, the significance of the power-frequency withstand voltage test is to assess the voltage endurance level of electrical equipment, so as to prevent accidents caused by insulation breakdown during operation due to voltage-related factors.

The test voltage for a withstand voltage test must be higher than the equipment’s normal operating voltage. For specific requirements, refer to the relevant national standards and specifications for high-voltage and low-voltage electrical equipment.
