Abstract

Apparatus detects an electrical fault in a primary tap having a plurality of distribution transformers each provided in a distribution circuit along a length of the primary tap, on a power distribution system. The apparatus includes a voltage monitor provided at each of the distribution circuits for monitoring a voltage in a corresponding distribution circuit, a controller in communication with each of the voltage monitor for receiving the voltage monitored and transmitted by the voltage monitors, and a fuse isolator configured to electrically connect the primary tap to a high voltage on the power distribution system and electrically disconnect the primary tap from the high voltage on power distribution system when activate. A fuse isolator actuator in communication with the controller is provided for activating the fuse isolator responsive to a control signal from the controller when a fault in the primary tap is detected by the controller, which determines that a fault exists in the primary tap based on the voltages monitored by the plurality of voltage monitors.
