SF6 Gas Circuit Breakers and Switchgear

Continuous monitoring and early leak detection

SF6 gas in your circuit breakers and switchgear is a direct indicator of equipment health. A leak is both an environmental risk and an early warning sign of deterioration. Continuous monitoring catches it long before it becomes an operational problem and gives you the basis for a safe phase-out.

High-voltage circuit breakers and switchgear are critical components in every substation. They protect the grid, enable safe switching operations and contain SF6 gas as an insulating medium. The condition of the gas is a direct indicator of equipment health: a pressure drop or a change in density is an early warning sign that something isn’t right.

The problem is that traditional inspections happen too infrequently. By the time a leak is discovered, it has often been going on for a long time, with both environmental impact and a risk of equipment failure as a result.

The EU ban on new SF6 equipment in medium-voltage networks came into force in January 2026, and from 2035 the restrictions will also apply to the servicing and maintenance of existing installations. This is a transition that takes time, and throughout this period, older circuit breakers and switchgear will remain in operation and require careful oversight.

We know that many grid operators are in the middle of this journey. Having full visibility of your circuit breakers and switchgear – what condition they’re in and how they change over time – isn’t just good practice; it’s what makes the transition manageable.

Gomero Connect connects to pressure or density sensors on your circuit breakers and switchgear and collects continuous data around the clock. Via Gomero Hub, the data is sent to Gomero Insights, where you see real-time status, trends over time, and receive automatic alerts, long before a leak reaches critical levels.

Your field technicians have all the information they need when they’re out at the substation. No manual logging, no paperwork, no uncertainty about what applies.

The solution is sensor-agnostic and works with all types of pressure and density sensors, making it future-proof even as the industry transitions to alternative insulating gases.

SF6 monitoring for circuit breakers and switchgear is part of Gomero Predict — our complete system for predictive maintenance of substations. You keep your existing systems; we add the intelligence layer. Start with one sensor, scale to your entire grid at your own pace.
