Product Description

SXGTU GIS Partial Discharge Withstand Voltage Test Device

The SXGTU is a high voltage test system designed to evaluate the insulation condition of Gas Insulated Switchgear through partial discharge and AC withstand tests. It is suitable for GIS manufacturers, power equipment testing centers and high voltage laboratories where controlled electrical stress and low background discharge are required.

The high voltage components are enclosed in a sealed and shielded structure to improve operational safety and reduce the influence of external interference. At rated voltage, the overall partial discharge can be controlled within 1–3 pC under normal conditions. Depending on the required test configuration, the system can generate high voltage through a test transformer or series resonance circuit.
