Description
Summary:An important task in the automation of distribution networks is the improvement of algorithms for single-phase ground fault (SGF) protection. Cable networks of 6-10 kV in many cases operate with a compensated neutral, when arc-suppressing reactors (ASR) compensate for the capacitive component of the SGF current at the fundamental frequency. At present, there are devices that also compensate for the harmonic and active components of the SGF current [1] . Therefore, the task of improving SGF protection is becoming more complicated.
