After electrification breakdownCapacitor plus working voltage breakdown, after the power off it is shown as non-breakdown, multimeter detection it does not show the characteristics of breakdown, the DC voltage at the two ends of the measuring capacitor is zero or very low under the condition of elec

Component leakageWhen the capacitor is leaking, the insulation performance between the two poles of the capacitor is decreased, the leakage resistance exists between the two poles, there is a DC current passing through the capacitor, the straightness of the capacitor becomes worse, and the capacity

Component breakdownAfter the capacitor breakdown, the function of the capacitor is lost, the path is between the two pins of the capacitor, the direct action of the capacitor disappears and the DC circuit of the circuit is broken down, thus affecting the AC working state.

Component open circuitAfter the capacitor is open, there is no function of the capacitor. After the capacitor in different circuits has an open circuit fault, the specific fault phenomenon of the circuit is different. For example, the AC sound appears after the filter capacitor is open, the coupling
