Testing methods for fixed capacitors

Testing methods for fixed capacitors

1. Detection of small capacitors below 10pF: Due to the small capacity of fixed capacitors below 10pF, measuring with a multimeter can only qualitatively check whether there is leakage, internal short circuit, or breakdown. When measuring, a multimeter R can be used × 10k gear, use two probes to connect any two pins of the capacitor, and the resistance value should be consistently high. If the measured resistance value (pointer swinging to the right) is zero, it indicates that the capacitor is damaged due to leakage or internal breakdown.

Precautions for using power capacitors

Precautions for using power capacitors

1 When installing capacitors, the wiring of each capacitor should be connected to the busbar using separate flexible wires, and hard busbar connections should not be used to prevent assembly stress from causing damage to the capacitor sleeve and damaging the seal, resulting in oil leakage.

The charging and discharging process of capacitors

The charging and discharging process of capacitors

(1) The process of charging. The process of charging a capacitor (storing charge and energy) is called charging. Connect one electrode plate of the capacitor to the positive pole of the power supply, and the other electrode plate to the negative pole of the power supply, and each electrode plate carries an equal amount of different charges. After charging, there is an electric field between the two plates of the capacitor, and the charging process stores the electrical energy obtained from the power source in the capacitor.
