PROCEDURE ESTABLISHING PARAMETERS OF INSULATION OF CABLE NETWORK WITH INSU LATED NEUTRAL Russian patent published in 2004 - IPC

Abstract RU 2230333 C2

FIELD: electrical measurement technology. SUBSTANCE: voltage of zero sequence is measured in agreement with procedure. Voltages between wires of phases of outgoing connections and ground are measured. Faulty phase is detected. Damaged connection is found. Outgoing connections are divided into two groups. Current of zero sequence of one group of outgoing connections is determined. Active contact resistance in point of fault and total capacitance of connections to ground are computed by measurement results. EFFECT: enhanced precision and authenticity of establishment of parameters of insulation of cable network in case of single-phase contact to ground. 3 cl, 1 dwg
