Measuring terminal, setting method of measuring terminal, ground fault point system

摘要

An electric device (e.g., a telescopic station) connected to the rear stage of the measurement terminal can correctly acquire information indicating the current and voltage output from the sensor.A plurality of locations on the distribution lineWhen a ground fault has occurred on the distribution lineInformation indicative of zero phase current and zero phase voltage output from a sensor for detecting the current and voltage of the power distribution lineCorresponding to the current time informationA measurement terminal for transmitting a ground fault point determining device to ground fault points to determine ground ground points of said distribution linesSaid sensor andElectrical equipment for obtaining information indicative of the current and voltage of said distribution line output from said sensor;To connect the measurement terminal betweenThe electrical device may correctly acquire information indicating the current and voltage of the distribution lineA setting circuit for setting the terminal impedance of the measurement terminal is provided.Fig.4
