GIS AC Resonant Test System for Partial Discharge and Withstand Voltage Testing, Variable Frequency High Voltage Test Equipment for GIS GIL and EHV Switchgear

The GIS AC Resonant Test System is engineered for high-voltage AC testing of large-capacitance GIS and GIL systems.

The variable-frequency resonant technology is particularly suitable for high-capacitance test objects and can be configured for factory and on-site testing.

• GIS AC withstand test
• GIS partial discharge test
• GIL AC withstand test
• Insulation withstand verification
• Variable-frequency resonance
• High-voltage measurement
• PD detection
• Automatic voltage regulation
• Test timing
• Data recording

Factory Type Testing

For GIS manufacturers performing product development and type tests.

Routine Factory Testing

For production-line or factory acceptance testing.

Site Commissioning

For newly installed GIS substations.

Maintenance Testing

For GIS equipment following major maintenance.

HIGHVOLT, for example, describes variable-frequency AC test systems for GIS routine/type testing, PD measurement and on-site testing, including direct connection to the GIS test object.
