The fault indicator type SPEF 3A2 C is used in association with disconnector terminal units (DTUs) for detection of short circuits, earth faults and phase discontinuity in distribution networks. The fault indicator functions as a data acquisition unit, which allows measured information and alarms from a DTU to be read by a remote control system. The information can be used, for example, for locating faults in the distribution network.
If no serial bus (SPA bus) is available, information can be obtained via the relay outputs and the analog outputs of the fault indicator.
