摘要

A method for determining the single-phase ground fault current in an isolated neutral network with a voltage of up to 1000 V is proposed. This method is based on measuring the values of the line voltage, phase voltages when additional capacitive conductivity connected between one of network's phases and ground. The error analysis showed that the developed method provides satisfactory accuracy in determining the single-phase ground fault current, as well as the simplicity and safety of work in existing electrical installations with voltages up to 1000 V.
