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.

Change voltage and frequency limits for power system transformation, says academic

Discussing next steps for government and industry following the launch of the Future Power System Architecture (FPSA) report, Taylor, who heads up the National Centre for Energy Systems Integration at Newcastle University, pointed to voltage and frequency limits as an easy target for rapid change.
