Gas Insulated Switchgear (GIS) Test Equipment

Merqab provides Gas Insulated Switchgear (GIS) test equipment used for the commissioning, maintenance, and diagnostics of GIS installations in HV and EHV substations. Our range includes partial discharge detection systems, SF6 gas analyzers, gas handling equipment, and insulation resistance test sets suitable for GIS applications. GIS installations require specialized test equipment due to the enclosed, gas-insulated design that prevents visual inspection. Partial discharge testing and SF6 gas analysis are essential for detecting insulation defects and gas leaks early, preventing costly failures and unplanned outages. Merqab's technical team works with substation engineers and utility companies to ensure the correct instruments are selected and that field teams are trained for safe and effective GIS testing.
