Capacitors

Pole top capacitors are connected to circuits to accept and store charges. They are used to help overhead distribution feeder systems operate more efficiently and reliably. Capacitors are found in substations and on poles.

A capacitor momentarily stores electricity to help control and improve voltage regulation. Should the voltage on a circuit fall below a specified level for some reason, the capacitor can momentarily maintain the voltage at line value. Basically, a capacitor serves the same purpose as a storage tank in a water system.

In a way, a capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. A battery has two terminals. Inside the battery, chemical reactions produce electrons on one terminal and absorb electrons on the other terminal. A capacitor is much simpler than a battery, as it can't produce new electrons -- it only stores them.

Pole Mounted Capacitor Banks provide power factor correction and voltage control on medium voltage industrial and utility electrical overhead systems.
