SYSTEM AND METHOD FOR AUTOMATIC HIGH RESISTANCE GROUND PULSE ACTIVATION AND DETECTION

A system for locating a ground fault in an HRG power distribution system includes an HRG pulsing system having a ground fault sensor to detect a ground fault, a pulsing contactor to introduce a pulsing current into the power distribution system, and a controller to control the pulsing contactor to introduce the pulsing current into the power distribution system in response to a ground fault detection by the ground fault sensor. Current sensors in the power distribution system monitor three-phase current signals on conductors of the power distribution system, with the current sensors positionedon distribution networks in the power distribution system and at a protection device included on each respective distribution network. A processor associated with each protection device and operablyconnected to the current sensors thereat receives signals from the current sensors for identifying a location of a ground fault in the power distribution system. 种用于定位HRG配电系统中接地故障的系统，包含：HRG脉冲系统，具有接地故障传感器以检测接地故障；脉冲接触器，用以将脉冲电流引入
