Power factor is a measure of how efficiently an AC (alternating current) power system uses the supplied power. It is defined as the ratio of real power (P) to apparent power (S), where the real power is the power that performs useful work in the load, and apparent power is the product of voltage (V) and current(I) in the.

We have seen that a capacitor bank is used for the improvement of power factor and reactive power compensation in a substation. As the role of this bank is very important, it becomes critical to see that the bank is maintained well. Also, it has to be seen which parameters of this bank should be specified for installing it into the substation.
Shunt capacitor banks are connected in parallel with the load or at specific points in the system, such as substations or feeders. They provide leading reactive power (positive Q) to cancel out or reduce the lagging reactive power (negative Q) caused by inductive loads, such as motors, transformers, etc.
Bank stability for a fuseless capacitor bank is similar to that of an externally fused capacitor bank and defined by shorted series sections, internal to individual capacitors. The voltage on the remaining series sections in the string should not exceed 110% of its rated voltage.
