G59/3-2 Protection Relay Panel Testing

Please be aware that G59/3-2 is now being used by most DNO Witness’s so your test and your control panel must comply with these recommendations. We have worked with most of the DNO engineers in the field and because of this we can provide a reliable testing service, and the correct test and test results which are much more exacting than the old tests.
Our Test Engineer is also the only person in the UK to train electricans to become G59/3-2 Test Engineers.
