Shunt power capacitors. Capacitors are used as shunts to redirect high frequency noise to ground before it can propagate to the load or other circuit components. Use in electronic filter circuits. It lags by 90 o to the active power.

The addition of switched capacitors not only improves the voltage levels but also provides an effective method of controlling the voltage levels. Power capacitors eatons cooper power series power capacitor products are designed for worldwide utility and industrial applications for system voltages from 24 kv through ehv. They also improve the voltage stability and reduce network losses.

The power required to run all the electrical appliances is the load as useful power is active power. Eaton produces capacitor subsystems for shunt series hvdc svc and filtering applications throughout the world. Improving the power factor also means a higher power transmission capability and increased control of the power flow.

Shunt capacitors affect the voltage rise when connected to the system. Shunt capacitors in improving power factor of load inductive components of a power system draw a lagging reactive power from the supply. The term is used in this context to distinguish the shunt components connected between the signal and return lines from the components connected in series along the signal line.

But decision should be taken in view of expenditure and utility. Of shunt power capacitors. Shunt capacitor banks are primarily used to improve the power factor in the network.

The installation of power capacitors enables a utility as will as the industrial customer to realize savings on their systems. Location of shunt capacitors the power factor improver capacitor can be installed at system bus distribution point and at load itself. The term shunt is used in filter and similar circuits with a ladder topology to refer to the components connected between the line and common.

In certain loads mainly in industrial load the entire load is switch on or off based on need. Shunt capacitors are usually called power factor correction capacitors although they also serve other functions and provide multiple benefits which will be discussed in the succeeding paragraphs.
