SXGTU GIS Partial Discharge Withstand Voltage Test Device
The SXGTU GIS AC Withstand Test System provides a high voltage solution for verifying the insulation strength of SF6 Gas Insulated Switchgear. It is designed for applications where GIS assemblies need to withstand specified AC test voltages during factory inspection, type testing or other high voltage verification procedures.
The system uses a sealed high voltage structure with internal shielding and supports single-stage voltage boosting. High voltage transformer boosting and series resonance can be selected according to the required test configuration, with both power-frequency and variable-frequency solutions available. The compact structure also helps reduce the space and power supply requirements of the complete testing installation.
