Product Description
SXGTU GIS Partial Discharge AC Withstand Test System
The SXGTU GIS Partial Discharge AC Withstand Test System is developed for high voltage testing applications requiring controlled partial discharge performance. The high voltage section is completely sealed within a shielded space, providing a reliable and safe structure for testing.
The overall partial discharge can be controlled within 1–3 pC at rated voltage under normal environmental conditions. The system adopts a compact design with lightweight components, reducing installation space requirements. High voltage generation can be achieved through high voltage transformer boosting and series resonance, including power-frequency and variable-frequency operation. The equipment also features an internal high voltage isolation switch, enabling one system for multiple testing arrangements.
