Abstract

The inventive method and device ensures a groundwire resistance measuring by a dead-earthed neutral in a network. A current flows from an alternating-current source 5 through a pull-up resistor 1 put in between a phase conductor and a groundwire 11. A current transformer 3 with the current ratio of 1 is used for creating a current in a neutral conductor that is equal to the load current and is oppositely directed theteto. The resistance of the groundwire is defined as a ratio of voltage measured by a voltmeter 4 on the secondary coil of the transformer and the load current measured by an ampermeter 2.
