In this paper a method for determining insulation parameters in an asymmetric network with a voltage of up to 1000 V for mining companies was developed. It is based on measuring the magnitude of the linear voltage, the phase-to-ground voltage, which has a minimum value before and after connecting capacitive additional conductivity between the phases of electrical network and the ground, and the phase angle between the phase-to-ground voltage vector and the linear voltage vector between other two phases.
