Why SF₆ Leakage Monitoring in Circuit Breakers
Sulfur hexafluoride (SF₆) is extensively utilized in circuit breakers and GIS/AIS substations because of its high dielectric strength, thermal stability, and arc-quenching capabilities. Although SF₆ insulated breakers are reliable, SF₆ leakage is a widespread issue, particularly in aging infrastructure. Minor leaks can undermine insulation integrity, system performance, and cause environmental emissions.Leaks usually happen at mechanical connections like valve fittings, flanges, bushings, or sometimes through material defects like poor aluminum casting.
SF₆ leakage monitoring allows for continuous monitoring of gas density and pressure, making early intervention possible before system performance is impaired. Monitoring systems help utilities detect and localize SF₆ leaks early using gas detection techniques—reducing maintenance, improving system reliability, and enabling environmental compliance. Through SF₆ leakage monitoring, utilities can increase breaker life, minimize unplanned outages, and support safe and sustainable grid operation.
Why Rugged Monitoring-
Rugged Monitoring’s SF₆ leakage monitoring in circuit breakers combines smart IoT sensors, robust edge devices, and advanced software to offer real-time insight into circuit breaker gas conditions. It continuously monitors critical parameters like SF₆ pressure, density, leak rate, time to refill, time to lockout, and dewpoint, allowing for early gas loss and insulation degradation detection.Our edge devices captures and process both analog and digital signals locally, ensuring reliable data acquisition even in harsh environments.
Also, Our system is flexible and can be configured to incorporate other breaker parameters like temperature, voltage, and current,for a comprehensive view of breaker condition.Our advanced software platform provides predictive analytics such as refill forecasting, lockout risk estimation, and trend analysis. With real-time SF₆ monitoring, Rugged Monitoring empowers asset managers to extend breaker life, minimizing unplanned outages, and ensure safer, more efficient operation while supporting environmental compliance.
