100kV to 1000kV GIS/GIL Gas-Insulated Transmission Line High Voltage Test System for Partial Discharge and AC Withstand Testing

Product Description

SXGTU GIS Partial Discharge Withstand Voltage Test Device

The SXGTU is a high voltage test system available in multiple voltage levels from 100 kV to 1000 kV. It is designed with a fully sealed high voltage section inside a shielded space, providing a compact structure for high voltage testing. Under rated voltage and normal environmental conditions, the overall partial discharge can be controlled within 1–3 pC.

The system covers capacity levels from 50 kVA to 2000 kVA, with higher ratings available for customization. High voltage can be generated using a high voltage transformer or series resonance, with power-frequency and variable-frequency options. All boosting methods adopt single-stage voltage boosting without cascade connection. Its compact size, lightweight components and convenient test-object connection make the system practical for high voltage test arrangements.
