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.

What is the function of a capacitor in a fluorescent light fitting?
A capacitor is used to improve the power factor of the lamp.More detailsTo prevent the lamp from taking too much current a fluorescent lamp has to have a choke, which has magnetic inductance. The inductance has a negative impact on the power factor of the (the ratio between apparent power and real power taken by the lamp) - i.e. the power factor is reduced - so a capacitor is used to compensate for the inductance by improving the power factor so that it is closer to the ideal value of 1.Basically the inductor with the capacitor smooths out the voltage or current.
How can calculate maximum demand load?
maximum demand load can be calculated as: # maximum demand=demand factor * Connected load or by # maximum demand = connected load * Diversity Factor Note: Demand factor and diversity factor are NOT same
How does poor power factor effect the supply system?
'Poor power factor' means that a load is drawing more load current is necessary for the amount of energy it consumes. The result is larger voltage drops along the supply lines and greater energy losses along those same lines. To overcome these problems, it would be necessary to install cables and other equipment with larger cross-sectional areas -this is expensive, so it's much easier and cheaper to improve the load's power factor. To encourage consumers to do so, utility companies include a surcharge if the power factor falls below a certain value. All of this only applies to industrial/commercial loads, it does NOT apply to residential loads.Poor power factor has the following effects on the power supply:High input currentover consumption of reactive energyIncrease in the cross sectional area of conductors
How much can you power on a 2.5kva generator?
It can supply 2.5 kW to a load with a power factor of 1. Otherwise the power available must be multiplied by the power factor which is always less than 1. If uncertain assume 0.8 which makes it 2 kW.
Advantage of a choke coil over a resistor in a power supply filter?
A choke is an inductor. For typical power frequency, an inductor will slightly change the power factor, but will not actively use much energy. An abnormal voltage spike on a power supply is equivalent to voltage at a much higher frequency. Inductors appear to be a much greater impedance to high frequencies. This allows the choke to pass "normal" power, while at the same time it blocks "abnormal" power.A resistor acts independent of frequency. It will limit the effects of the high frequency voltage spikes by dissipating their energy, but it will do the same for the normal power system frequency. In effect, it is always using power, when the choke only uses what you don't want to get to the power supply.
How much energy is carried by electricity?
For DC, the power (energy/time) is calculate as: P = IV (power = current x voltage) For AC, the correct formula is: P = I x V x (power factor) However, the power factor is often close to one, so you can usually just use the IV product.
What is the relationship between energy power and time?
Power is the rate of moving energy. Power = (amount of energy moved) divided by (time to move that much energy)
How much energy does produced when 50 coulombs of charge passes a motor when it it connected to a 14v source?
50 Coulomb = 50 Ampere x second. Power (in watt) can be calculated by multiplying volt x amperes x (power factor). Since the power factor is not specified, you may assume a factor of 1 - this is often a good approximation. Therefore, watt = volt x amperes. Energy (in joules) = power (in watts) x time (in seconds). Perhaps you can figure it out from there.
If current in an electric stove is doubled how will the thermal energy produced per unit time change?
P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.
How much power in a 15000 kva transformer?
The power in a 15 MVA (15000 KVA) transformer depends on the power factor. You did not specify the power factor, so I will assume a power factor of 0.92. Simply multiply MVA by PF and you get 13.8 MW.
How much energy does Germany have?
the power of pie gives germany the full power and energy to do all jk
Why should always be power factor less than 1?
Power factor can also be equal to 1. Power is greatest when voltage and current are in phase; the "power factor" is used to specify how much less the power is, compared to the product of voltage x current, if they are not.
