Diagnosis of overall 10kV cable insulation state based on transient voltage transfer characteristics
The online detection of the cable insulation status is of great significance to ensure the stable operation of the cable. Based on the transmission characteristics of the transient voltage in the cable, this paper proposes a method for detecting the cable insulation state. By establishing the cable distributed parameter model, the relationship between the cable transfer function and the insulation parameters is theoretically deduced. A simulation test platform for cable insulation testing was built based on PSCAD, and the aging of the cable insulation was simulated by changing the thickness of the cable insulation layer and the relative permittivity. The simulation results verified the feasibility of the method.
