GIS AC Hipot Test System and Partial Discharge Detector for 145kV 245kV 420kV 550kV GIS Switchgear Insulation Testing

The GIS AC Hipot Test System and Partial Discharge Detector is designed for high-voltage GIS insulation testing across different voltage classes.

The system can be configured according to the customer's GIS rated voltage and required test voltage.

• 72.5 kV
• 126 kV
• 145 kV
• 170 kV
• 245 kV
• 252 kV
• 362 kV
• 420 kV
• 550 kV
• Higher voltage classes

Important: the exact AC test voltage must be determined according to the applicable GIS standard, rated voltage, insulation level and project specification rather than simply selecting the highest voltage class.

• AC hipot test
• AC withstand voltage
• Partial discharge detection
• PD pattern analysis
• Insulation verification
• High-voltage measurement
• Automatic test control
• Test data storage

“Our GIS is 145kV/245kV/420kV. Which system should we choose?"

The rated voltage alone is not enough.

We normally need:

GIS rated voltage + required test voltage + GIS capacitance + test duration + frequency requirement + applicable standard.
