Szukana fraza: [Abstrakt = "The article focuses on problems related to earth faults in the MV network of an intermittent character. There are situations in which the neutral point of the network is grounded through a resistor or coil with Active Current Forcing Automation \(AWSCz\) analysed. The study relate primarily to current and voltage waveforms on selected lines in network, values and time course of symmetrical components of these values and parameters characteristic of the earth fault. In the simulation the average value of the selected signals is calculated. This is to assessing the possibility to detect earth faults by modem IED. It was evaluated for the possibility of applying the admittance criteria to detect intermittent earth faults in particular with regard to the earth fault passage indicators."]
