Improving the power factor of an industrial load acts to reduce the load current delivered by the electricity utility company, enabling them to reduce the amount of copper used in the supply lines, Transformers, circuit breakers, etc. It also prevents the electricity utility company imposing a penalty charge applied to the factory's energy bill.
The most common method of improving power factor under these circumstances, is by installing a capacitor bank at the supply's point of entry at the factory. It is also possible to install capacitors at individual inductive loads.
Power factor improvement does not apply to residential loads, and any company offering 'power-factor improvement' capacitors for residential loads is a scam.

How power factor helps to improve circuit?
Improving power factor does nothing to improve a circuit. It merely affects the amount of current drawn by the load.
Why the power factor improves with the load?
Power factor doesn't necessarily 'improve with the load', but it is determined by the load.

Why inductor is used in electrical circuit?
To improve the power factor
What is a method to improve the power factor?
Add capacitors from line to ground.
Can we improve generator power factor for increasing active power?
The 0.8 Power Factor provided by generator manufacturers is not the load power factor, but it is the nominal power factor used to calculate the kW output of an engine to supply the power for a particular alternator kVA output. Alternators are therefore designed to supply their rated kVA at 0.8 lagging power factor.
How select the rating of capacitor with respect to KW for improving power factor?
The capacitors must be sized according to the reactive power being used, not the real power being used, to improve power factor.
A factor that led to the growth of the factory system in the US was the development of power. True or False?
True(OW)
When you should use synchronous motor instead of capacitor for power factor correction?
Synchronous motors show some interesting properties, which finds applications in power factor correction. The synchronous motor can be run at lagging, unity or leading power factor. The control is with the field excitation, as described below:When the field excitation voltage is decreased, the motor runs in lagging power factor. The power factor by which the motor lags varies directly with the drop in excitation voltage. This condition is called under-excitation.When the field excitation voltage is made equal to the rated voltage, the motor runs at unity power factor.When the field excitation voltage is increased above the rated voltage, the motor runs at leading power factor. And the power factor by which the motor leads varies directly with the increase in field excitation voltage. This condition is called over-excitation.The most basic property of sycho motor is that it can be use as a CAPACITOR OR INDUCTOR both. Hence in turn it improves the power factor of system.The leading power factor operation of synchronous motor finds application in power factor correction. Normally, all the loads connected to the power supply grid run in lagging power factor, which increases reactive power consumption in the grid, thus contributing to additional losses. In such cases, a synchronous motor with no load is connected to the grid and is run over-excited, so that the leading power factor created by synchronous motor compensates the existing lagging power factor in the grid and the overall power factor is brought close to 1 (unity power factor). If unity power factor is maintained in a grid, reactive power losses diminish to zero, increasing the efficiency of the grid. This operation of synchronous motor in over-excited mode to correct the power factor is sometimes called as Synchronous_condenser.
