Product Description
GIS Partial Discharge AC Withstand Test System
The SXGTU GIS Partial Discharge AC Withstand Test System is designed for high voltage partial discharge and withstand testing of GIS equipment. The high voltage section is fully sealed within a shielded space, providing a safe and reliable testing structure.
The system can control the overall partial discharge within 1–3 pC at rated voltage under normal environmental conditions. It supports high voltage generation through high voltage transformer boosting and series resonance, including power-frequency and variable-frequency operation. With a compact structure, lightweight components, and convenient connection with the test object, the system is suitable for high voltage testing applications requiring reliable performance.
