Switching elements such as circuit breakers, load switches or disconnectors can be found in both air-insulated and gas-insulated switchgear (GIS). Circuit breakers are particularly important - especially in the event of a grid malfunction, when they must reliably disconnect fault currents of many kiloamps within just a few milliseconds, after having stood still, often for years.

“The OMICRON proved to be the best because it is user-friendly. You connect it to the switchgear, switch it on, you press Start, Measurement, you have a result.”

Grounded Contact Resistance (GCR) Measurement on GIS
Despite its reliable design, condition assessment of GIS is becoming more and more important as the average age of existing GIS systems move toward the end of their life expectancy. One of the most common non-invasive breaker condition assessment methods is the static contact resistance measurement.
During the GCR measurement method, the GIS is grounded on both sides before it is measured with CIBANO 500. GCR combined with the already established current sensor measurement (CSM) method for timing measurements now allows users to accurately measure timing and contact resistance while the GIS is both sides grounded, significantly increasing operator safety.
