APPLICATIONS OF CAPACITORS

1. Industrial Applications:-

Capacitors are installed in industries for the improvement of power factor, improvement of voltage, reduction  in energy loss, etc.

2. Switching with induction motors:-

Capacitors are generally applied to induction motor terminals, to help them during the switching on period. 

Of course, while using this technique, certain precautions are necessary, and a suitable size of the capacitor has to be determined for different motor ratings,

3. Series induction:-

In order to improve the voltage regulation of a line, a capacitor is used in series with the line to compensate for the line reactance.

4. Induction heating:-

Capacitors are extensively used in heating for supplying exiting current to induction heating equipment.

5. Miscellaneous applications:-

Capacitors are also used in resistance-type welders to compensate for the welder reactance, and to improve the power factor.

Induction accelerators used in nuclear research, such as Betatrons and Synchrotrons, require excitation for large a.c. magnets.

Capacitors are also used in florescent ballasts for improving power-factor, as by-pass capacitor and blocking capacitors in electronic circuits.

For storage of energy such as in welding and flash photography.
