Determining conductance of an insulation with respect to earth of 6-35 kV networks with insulated neutral

摘要

Calculation formulae for determining the insulation parameters with respect to earth for 6 - 35kV distribution networks with an insulated neutral on the basis of measuring the network regime parameters are given. The formulae proposed make it possible to determine the parameters of an insulation of network phases with respect to earth without breaking the network operation regime with account taken of the influence of devices for compensating reactive power and asymmetry of voltages and currents. Method for investigating errors of the formulae are proposed.
