capacitor bank

A capacitor bank is a buffer device in power distribution networks. It consists of many identical capacitors connected in parallel or in series, which is used at strategic network points, improves the power factor and counteracts unwanted phase shifts

. capacitor banks can be used in high, medium and low voltage as static reactive power compensators

, in powerdistribution networks of power utilities and in industrial power distribution systems. They can also be used in DC voltage networks as energy storage, to balance voltage peaks and to reduce ripple

. They provide voltage profile and current flow improvement in power distribution systems.

Depending on the function and the power grid, such capacitor banks can have capacities of several mega joules and can deliver peak currents of several hundred kilo amperes in a few hundred milliseconds.
