Learn about Hipot testing, common testing devices (Series Resonant, AC/DC Withstand, and VLF), and their differences for high-voltage equipment testing.

Although the series resonance test device has undergone strict quality inspection before leaving the factory, various faults may still be encountered during the test due to the complex and changeable on-site environment. The above content provides analysis and treatment suggestions for common faults to help testers solve problems more quickly and accurately.
