This paper made analysis on the topic of Low-voltage network that contacts parallel resonance system with cable. A new method in detecting insulation parameters was presented through added testing resistance in single phase. The corresponding circuit model is established and the theory is proved that there is linearity among resonance capacitance, inductance and insulated resistance. Simulation study was carried out in this paper. The research shows: the testing error of this insulation detection method is within±0.5% which has high accuracy.
