Ten faults of capacitors(8)

In general, the capacitance doesn't make a loud noise when it's running, a bit like the buzzing sound of a bee's cauliflower. However, there are still some anomalies, mainly:

(1) The discharge sound caused by the loosening of the connection between the capacitor busbar and the conductive bar;

(2) Discharge sound caused by aging or overvoltage breakdown of internal components of capacitors;

(3) Noise caused by high order oblique wave intrusion; The closing inrush produced when the container set is put into operation will also make an abnormal sound from the capacitor.
