Abstract and keywords

Abstract (English):
The results of simulation modeling of a 10 kV distribution network are presented. It is shown that with single-phase earth closures, a stable sign of the presence of damage on the feeder in the form of an intermittent arc is the composition of higher harmonics.

Keywords:
single-phase earth fault, frequency characteristics of overhead lines, resonant harmonics of current and voltage, fault location, electrical networks
