The identification of high-impedance earth-faults in MV network is a very difficult due to low level of measurement signals for commonly used protections operation scheme. New method of high resistance fault detection based on additional signal injection in neutral point of the network is presented in this paper.
This paper presents modern applicable methods of measurement of the earth-fault parameter of the MV network. Methods based on additional source of forcing of the network voltage asymmetry are described. The aspects of practical use of such methods are revealed. The notes of exploitation experience of authors with use of devices utilizating these methods are presented.
