SF6 GIS Partial Discharge and AC Withstand Test System for High Voltage Electrical Equipment Gas Insulated Switchgear Insulation Testing

Product Description

SXGTU GIS Partial Discharge Withstand Voltage Test Device

The SXGTU GIS Partial Discharge and AC Withstand Test System is designed for high voltage insulation testing. The high voltage section is fully sealed inside a shielded space, providing a safer and more reliable test structure. The overall partial discharge can be controlled within 1–3 pC at rated voltage under normal environmental conditions.

The system is available in voltage levels from 100 kV to 1000 kV and capacities from 50 kVA to 2000 kVA. High voltage can be generated through a high voltage transformer or series resonance at power frequency or variable frequency. All voltage boosting methods use single-stage boosting without cascade connection. The compact structure requires less installation space and offers convenient connection with the test object.
