Circuit breaker testing with OMICRON

During the last few years we have seen an increasing demand for non-invasive test methods for evaluating the condition of circuit breakers. Regardless if the circuit breaker is installed in a conventional substation, a switchgear or a Gas Insulated Substation (GIS), the industry has moved to try to perform a complete diagnostic without intervening any working connection; that means, testing both sides grounded systems and taking measurements without disconnecting secondary cables of the circuit breaker.

Substation monitoring has been an area of interest amongst distribution network operators (DNOs) for some time, as the way consumers use and interact with the network changes due to the relatively rapid growth of photovoltaic installations, electric vehicles, domestic-level battery storage and so on. Before these relatively new technologies were widely adopted, it was sufficient to manually record a reading from an analogue maximum demand indicator during a physical inspection once or twice a year, but this is no longer considered sufficient by many in the industry who are now interested in annual and diurnal patterns, harmonics and more.
