Current and voltage sensors or detectors, to be used for fault passage indication purposes - General principles and requirements has-corrigendum in-service inspectionWhat is BS EN 62689 1 Current and voltage sensors about? BS EN 62689 1 is a safety standard on current and voltage sensors or detectors. BS EN 62689 1 defines the minimum requirements (therefore performances) and consequent classification and tests (except for functional and communication ones) for fault passage indicators (FPIs) and distribution substation units (DSUs) (including their current and or voltage sensors), which are, respectively, a
