Moisture Risks & Early Signs of GIS Degradation
Gas Insulated Switchgear is built for reliability — but even small amounts of moisture can quietly undermine its performance.
If left untreated, it leads to:
- Insulation breakdown
- Faults & flashovers
- Corrosion & contamination
- Reduced equipment life
Signs of GIS degradation you can’t ignore:
- Rising dew point readings inside compartments
- Condensation visible on viewports or fittings
- Frequent alarms from moisture sensors
- Unstable pressure or minor SF₆ leaks
- Increased partial discharge activity
Even if your assets appear to be running smoothly, these warning signs mean risk is already building inside your system.
The traditional fix isn’t practical
The smarter way forward is EMT Gas-Dry
