EEMUA Webinar - Wanting a clean break? Magnetron tests for ageing vacuum circuit breakers

The introduction of commercially viable vacuum circuit breakers, somewhat more than 40 years ago, was revolutionary in terms of reduction in maintenance tasks, improved reliability and compactness. However the early installations are now suffering the ravages of time and use – but how badly and how much life is likely to be left? To answer these questions it isn’t possible to just open one up to look. Magnetron testing can provide answers. In this webinar, we look at the technique itself, what it can do, what it requires and what are its limitations.
