COMPARISON OF METHODS FOR CALCULATING THE CURRENT OF SINGLE-PHASE EARTH FAULT IN ELECTRIC NETWORKS 6-10 KV OF A COAL MINING ENTERPRISE
The paper presents the results of a comparative analysis of the accuracy of the existing methods for determining the capacitive current relative to the ground for a 6 kV distribution network of a mining enterprise. The calculation of the capacitive currents flowing in the outgoing connections of the electrical network in the mode of a single-phase earth fault has been made using various existing methods. The experiment of a single-phase earth fault in the operating distribution network was carried out, according to the results of which the obtained values of the capacitive currents made it possible to establish the errors of the known calculation methods.
