For residential load, power-factor improvement is irrelevant as it will make no difference to the quantity of energy consumed and, therefore, the electricity bill.
For industrial/commercial consumers, poor power factor results in additional charges over and above those for the amount of energy consumed. The electricity supplier will specify a value below which these additional charges will be imposed, so it's in the interests of the consumer to ensure the power factor of their loads doesn't fall below that agreed value.
What else can I help you with?
What equipment used in power factor improvement?
The simplest method of power-factor improvement is by using appropriate capacitors, connected in parallel with the load. Power-factor improvement capacitors are rated in reactive volt amperes, not farads.
What is PFI panel?
Power Factor Improvement Panel. It controls power factor
How do you connect the capacitor bank in electrical system?
improvement of power factor
How do you hook up capacitors for power factor correction?
The voltage across a purely inductive load leads the current by 90 degrees.Because of this 90 degree offset the power transfer is inefficient because the current and voltage peaks are never aligned.P = I * ETherefore a capacitor with an reactance equivalent in magnitude but opposite in polarity to that of the inductive load at the operating frequency can be placed in parallel with the load to maximize power transfer.CommentPower-factor improvement does not improve, or increase the efficiency of, power transfer. The power of a load is exactly the same after power-factor improvement as it was before power-factor improvement. All that power-factor improvement does is to reduce the amount of load current.

Do capacitor devices actually save power?
Your question should read, "Do capacitive devices actually save energy?" Power is simply the rate at which you use energy, so you cannot 'save' power. And the answer to your question is no.Capacitor banks are used to improve the power factor of industrial loads. Power-factor improvement acts to reduce the load current, thus reducing the amount of copper required in the supply system conductors, transformers, etc. Power-factor improvement, on the other hand, has no effect upon the operation of the load. The energy used by the load after power-factor improvement is exactly the same as it was before.Power-factor improvement only really applies to industrial loads, because utility companies will financially penalise industrial consumers who allow their power factor to fall below an agreed figure. Power-factor improvement will have absolutely no effect whatsoever on residential loads, so companies trying to sell you 'capacitor devices' that promise to 'save you money' are scam merchants!
Can i reduce electric bill by improving power-factor?
For a residential consumer, power-factor improvement has absolutely no effect on one's electricity bill. Adding power-factor improvement capacitors at the point of supply will have absolutely no effect upon the operation of the load circuits, but it may act to reduce the supply current. But reducing the supply current will not reduce one's energy consumption.
What is the actual 50KW load after improvement of the power factor from 0.68 to 0.99?
Sorry brother it"s to difficult
Will the improvement of power factor will increase the efficiency?
Efficiency is defined as the ratio between the output power and the input power of a machine, expressed as a per unit or percentage. Power factor improvement has absolutely no effect on the behaviour of a load. All it does is to reduce the magnitude of the load current. A reduction in load current means that less copper can be used in the supply of energy to the load. However, it doesn't effect either the output or input power of the load. So the answer is no, power factor has no effect on the efficiency of a load. You could argue, however, that if improving the power factor of a load reduces the supply current, leading to lower line losses, then there is an improvement in the efficiency of the supply system.
How do you install capacitor bank?
It depends what it's for. If it's for power-factor improvement, then it is normally connected in parallel with the load.
Why alternator power factor 0.8?
In terms of generators, the alternate power factor is generally 0.8 for most models. This factor is defined as the power needed to operate within the limits of he generator capability curve.
What are the importance of capacitors?
It depends on the purpose where you are using the Capacitor.If you are using in power systems then it may be used for improvement of Power factor.Which is the important factor in industry.
