GIS Insulation Test Equipment with Partial Discharge Detection – High Voltage AC Test System for Gas Insulated Switchgear Factory and Field Testing

The GIS Insulation Test Equipment is designed to evaluate the electrical insulation condition of gas-insulated switchgear during manufacturing, installation, commissioning and maintenance.

A complete GIS insulation testing solution can combine a high-voltage AC source with partial discharge measurement to provide both dielectric withstand verification and insulation diagnostics.

This is especially valuable when customers need to identify potential insulation problems before they develop into operational failures.

• High-voltage AC insulation testing
• AC withstand voltage testing
• Partial discharge measurement
• PD inception voltage detection
• PD extinction voltage detection
• Discharge magnitude measurement
• PRPD pattern analysis
• UHF signal detection
• GIS commissioning testing
• GIS factory testing
• Preventive maintenance testing

Depending on the configuration and diagnostic method, GIS PD testing can help engineers investigate:

• Metallic particle defects
• Protrusion defects
• Floating electrode defects
• Surface discharge
• Insulation abnormalities
• Assembly-related defects
• Abnormal electromagnetic interference

Experimental GIS test platforms commonly use artificial defects such as metal particles, floating potential and protrusions to study different PD characteristics.
