Abstract

The article conducted experimental studies of the developed method for determining insulation parameters in an asymmetric network with a voltage of up to 1000 V for mining enterprises, based on measuring the magnitudes of the linear voltage modules, the phase angle between the phase voltage vector relative to earth and the phase phase linear vector larger than the measured phase voltage relative to earth, as well as the voltage of the phase relative to earth, which has a minimum value before and after connecting the capacitive additional conductivity between the electrical phases network and earth. Experimental studies have shown that the developed method for determining insulation parameters has a satisfactory accuracy, simplicity and safety of work in electrical installations during operation of electrical installations with voltage up to 1000 V
