| Abstract: | In order to analyze the variations of parameters for insulation aging fault of 10 kV bus bar,bases on Power system Computer Aided Design(PSCAD), by simulation for insulation aging of 10 kVclosed bus bar, finds out the relation curves among the earth wire current of single-phase andthree-phases bus bar with the insulation capacitance, insulation resistance and dielectric loss angulartangent value. The result shows that the simulation calculation and analysis can offer effectively gistfor monitoring 10 kV bus bar insulation aging trend, and preventing the fault bringed by bus bar insula?tion aging. |
