中文版The insulation level is to correctly deal with the relationship between various voltages (including operating voltage and various overvoltage), various voltage limiting measures and insulation strength acting on the insulation. Strive to make the products safe and economical, and get good economic benefits. In terms of insulation, the main faults are external insulation to ground flashover and breakdown, internal insulation to ground flashover and breakdown, interphase insulation flashover and breakdown, lightning overvoltage flashover and breakdown, porcelain insulator bushing, capacitor bushing flashover, pollution flashover, breakdown, lifting rod flashover, CT flashover, breakdown, porcelain insulator fracture, etc.
