Compact Stability.
Schneider Electric’s GMA GIS is built for 24 kV performance — delivering maximum uptime in a minimum footprint.
Loose Joints.
Big Risks.
Older MV panels hide insulation wear and drift in interlocks. That leads to unsafe switching and unexplained trips.
Hidden hot spots
Insulation wear creates localized heating that standard sensors miss.
No continuous monitoring
Blind spots between inspections grow into unpredictable outages.
Loose MV joints
Thermal cycling and vibration loosen critical primary power connections.
Ageing mechanism wear
Internal interlocks drift over time, risking unsafe manual operations.
Limited fault insight
Older MV panels hide degradation until a catastrophic failure occurs.
