Causes of High Voltage Ceramic Capacitors Having Porcelain Insulation Surface Flashover

The cause of flashover on the porcelain insulating surface of the high-voltage ceramic capacitor in the circuit is: surface contamination, environmental pollution, bad weather (such as rain, snow) and over-voltage will cause surface flashover to cause damage or tripping of the capacitor . The capacitor bank should be cleaned periodically and protective measures should be taken in the dirty areas. Daily necessary inspections must be done to ensure that high-voltage ceramic capacitors can be used normally.
