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
