What 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 device or a device/combination of devices and/or functions able to detect faults and provide indications about their localization. By localization of the fault is meant the fault position with respect to the FPI/DSU installation The point on t...
