What is the effect of power factor on the cost of generation?
The effect of low (or 'poor') power factor is that a given load requires more load current than at high power factors. So, to accommodate these higher currents, a greater volume of copper is required in the supply cables, switchgear, transformers, etc. So much greater capital costs are required if low power loads are supplied.
Does raising the power factor of a residence result in dollar savings on your electric bill?
No. Your energy meter monitors the supply voltage and the in-phase component of the load current, so improving your power factor will have no effect on your energy consumption and, therefore, your electricity bill.
What is the Measurement of power energy power factor?
Power - Watt. Energy - Watt Hour. Power factor - no unit. just number less than or equal to 1.
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.
Can power factor greater than 1?
not possible. power factor is an cosine angle between current and voltage...
How does power factor affect your power bill?
A poor power factor causes the meter to rotate more slowly than it should, so a poor power factor would reduce your bill. Electric utilities compensate for this in commercial services by billing based on power factor, or they install a meter that actually measures power factor.AnswerEnergy meters 'read' the in-phase component of load current (therefore the load's 'true power' multiplied by time) and, so, are completely unaffected by the power factor of a load. So the power factor of a residential load will have absolutely no effect whatsoever on that residence's 'energy' (not 'power') bill.Industrial and commercial consumers are billed for 'demand' (their rate of consumption of energy -i.e. the power) as well as energy supplied'. In addition, these consumers are usually penalised if the power factor of their load falls below an agreed value. So power factor does affect the overall bill (but not the energy bill) of industrial consumers.
Is this true that power factor for electrical energy is 0.8 and for mechanical energy is 0.8x0.6?
For electrical energy - basically for AC circuits - the power factor can be anything between 0 and 1. In many practical situations it's close to one. "Power factor" has nothing to do with mechanical energy.
How much energy you can save by improving the power factor from 0.8 to 0.98?
None. Power factor improvement has no effect whatsoever in saving energy. <<>> What it can save you is money. A utility company will charge an additional cost on your regular bill for having a low power factor reading less than .92 depending on the type of service. It is billed as a surcharge to the addition cost of the bill. On three phase services this correction can be done by adding capacitance to bring the power factor up to .92.
Power factor is not greater than unity?
Yes. Power factor is never greater than one, nor less than negative one. It is the cosine of the phase angle, and is the ratio of true versus apparent power.A negative power factor can occur in the case of a generator.
What is the effect of induction motor on power factor?
An induction motor has a lagging power factor. Motors of more than about 2 HP are designed to have a power factor of 0.85 or higher.
What is the excessive use of conventional energy?
energy can be in forms of heat light and sun as well as energy resources like electricity,gas,power,water and etc. if these energy resources are used excessively it will have greater effect on man,s life and routine.
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!
