Product Description
SXGTU GIS Partial Discharge AC Withstand Test System
The SXGTU GIS Partial Discharge AC Withstand Test System is designed for high voltage insulation and withstand testing. The equipment adopts a fully sealed high voltage structure within a shielded space, ensuring safe and reliable operation during testing.
The system covers voltage levels from 100 kV to 1000 kV and capacity levels from 50 kVA to 2000 kVA. The overall partial discharge can be controlled within 1–3 pC at rated voltage under normal environmental conditions. High voltage generation methods include high voltage transformer boosting and series resonance, with power-frequency and variable-frequency operation available. The system uses single-stage voltage boosting and provides convenient connection with the test object.
