LOW VOLTAGE NETWORKS INSULATION MONITORING WITH TWO AND THREE VOLTMETER READOUTS METHODS

Purpose. In the paper there are described methods of two and three voltmeter readouts for insulation resistance periodic measurement in live DC and AC/DC IT networks. A new measuring method for AC/DC networks is proposed. Application of a novel algorithm for shortening of measurement cycle is explai...
