PROCEDURE FOR TESTING SAFETY OF ELECTRIC DEVICES WITH INSTALLED ACTIVE ARRESTERS

摘要

A procedure for testing the safety of electric devices with installed active arresters or active RCDs is characterised in that a holistic test of electric equipment with installed active arrester or active RCD can be carried out according to this procedure. It is characteristic for the procedure that it connects suitable sources of signals and measuring circuits with measuring couplings (test socket and IEC connection) to enable a quick, safe and unharmful execution f the holistic test without switching over and to keep the active arrester or active RCD switched on until necessary.
