Pinpoint Flashovers in Seconds: Restore Power Faster
A fixture in modern substations, Gas Insulated Switchgear (GIS), serves as the backbone interconnecting other assets. When insulation defects grow into flashovers, they can black out a substation and the community who depends on it for hours or even days. Qualitrol’s new Arc Detection & Localization upgrade for its Gen3 Partial Discharge (PD) Monitoring System turns days and hours into minutes. Saving time, saving resources, and keeping the lights on.
Why This Matters
- Locate faults instantly – The same UHF sensors already utilized for PD can now be used to pinpoint the gas compartment where a flashover occurs. No extra hardware, no guesswork.
- Cut recovery time by 80% or more – Operators can re-energize healthy bays faster, slashing outage duration and demands on your maintenance team.
- One dashboard, comprehensive GIS health – PD trends, gas density, and arc location all sit in a single view, so teams plan repairs, not scavenger hunts.
- Safety first – Early fixes mean less time on site and a safer crew.
How It Works
- Detect – Gen3 Arc algorithms utilize UHF signals to identify flashovers
- Classify – Built-in defect libraries sort out normal circuit breaker operations from true flashovers
- Pinpoint – The system triangulates the location of the flashover and notifies the user
The Payoff
Every minute of uptime, and every failure prevented, is measured in thousands or millions of dollars – and in grid confidence. With Arc Detection and Localization, Qualitrol enhances the platform trusted for over 20 years to identify partial discharge and now enables users to locate flashovers in real time.
