The power required to run all the electrical appliances is the load as useful power is active power. The active power is expressed in kW or MW. The maximum load connected to the electrical power system is mainly inductive in nature such as electrical transformer, induction motors, synchronous motor, electric furnaces, fluorescent lighting are all inductive in nature.

In addition to these, inductance of different lines also contributes inductance to the system.

Because of these inductances, the system current lags behind system voltage. As the lagging angle between voltage and current increases, the power factor of the system decreases. As the electrical power factor decreases, for same active power demand the system draws more current from source. More current causes, more line losses.

Poor electrical power factor causes poor voltage regulation. So to avoid these difficulties, the electrical power factor of the system to be improved. As a capacitor causes current to lead the voltage, capacitive reactance can be used to cancel the inductive reactance of the system.

The capacitor reactance can be used to cancel the inductive reactance of the system.
