The energy supply sector is another area in which an ongoing trend away from purely time-based towards condition-based maintenance has been observed. To be able to carry out a rapid analysis in space-saving gas-insulated switchgear (GIS), a plant operator requires devices and testing methods that perform the analyses in an efficient, non-invasive way. This paper describes new measurement methods that enable timing measurements in GIS installations without having to take the installations out of service. This minimizes the downtimes associated with circuit breaker testing and enables potential time and cost savings.
