Power factor is the percentage of actual useful energy obtained from an electrical device as opposed to the wasted energy lost to impedience of a circuit. ie heat, voltage drop. Improvement is to raise this percentage to as close to 100% as possible.

What is the use of synchronous machines in power grid system?
To improve the power factor
Why inductor is used in electrical circuit?
To improve the power factor
Is it possible to transmit power with leading power factor?
The power factor depends on the properties of the load, and if any power factor correction is done it has to happen at the load, so that the current in the transmission lines is reduced. Correcting the power factor at the sending end fails to address the problem.
Is it advisable to correct the power factor to unity?
power factor depends on the load being fed if the load is entirely resistive power factor will be unity ..if the load includes an inductor or capacitpr due to phase displacement between v and i the pf will be lag or lead respectievly
How you improve power factor in synchronous motor?
Power Factor measures the difference in phase between the current and voltage. When they are in phase the Power Factor is defined as 1. When out of phase the value is less than 1. If they are 180 degrees out of phase the Power Factor will be zero.
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 does a capacitor improve power factor?
yes power capacitar ust inprove the power factor and sae the kvah reding
What is the technique of improve the power factor?
Simple technique by adding PP capacitor with automatic power factor controller.
What is the use of synchronous machines in power grid system?
To improve the power factor
Can the capacitor be inserted in series in order to improve the power factor?
In a circut we use capacitor in series for improving power factor
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.
How do you improve the quality of a PowerPoint?
You can improve the quality of a Power point. This can be done by adding more features and add-on.
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.
What is your opinion whether a low power factor can damage 20 watt led lights installed in a hotel?
The load (in this case, your led lighting) determines its own power factor. While you can improve the power factor (move it towards unity) at the terminals, you are not actually changing the power factor of the load.
