# What is the meaning of load factor?

"Load Factor" is an indicator of how steady an electrical load is over time.

If your electric billing rate includes both an Energy (kWh) and Demand (kW) charge, your load factor can be calculated by the following formula:

L.F. (percent) = [(Total kWh)/(# Days in Bill Cycle x 24 hrs/day)]/[Peak kW Demand]

If your load factor is low, you should look for ways to even out your electrical usage (i.e., shift energy intensive processes to periods of otherwise low usage).

By increasing load factor, you will reduce the impact of monthly demand (kW) charges on your bill.

Another way of looking at load factor is:

LF = average demand / peak demand

for a given period of time.

Load factor is the total energy consumed in a period (kWh) over maximum power that can be delivered(kW) in to no of hours (h) in that period.

Load factor = Energy consumed (kWh)/ max power (kW) x No. of hours (h)

### How load factor is used?

Ratio of Average load to Maximum demand for a given period (for a day, month or year) is termed as Load factor or Plant Load Factor (PLF). Load Factor = Avg. Load*24/Max Demand*24 ......... For a Day. This Load factor is very important in the sense of calculating the overall generation cost. It is always less than 1. Higher the LOAD FACTOR of a power station,lesser the overall per unit generation cost of the power…

### How do you differentiate inductive loadcapacitive load resistive load which basics?

For an inductive load, the current lags the voltage by 90 degs. Hence the power factor for an inductive load is 0. For a capacitive load, the current leads the voltage by 90 degs. Hence the power factor for a capacitive load is 0. For a resistive load, the current and the voltage are in phase. Hence the power factor for a resistive load is 1.

### Why can a reactive power load drop the voltage more than the active power load in a transmission line?

A load with a poor power factor draws extra current from the power supply, meaning that there will be more of a voltage-drop in the supply. As an example, if the load is 6 kW on a 240 v supply, the current drawn is 25 amps if the load has a power factor of 1. The kVA is equal to the kW. But if the load has a power factor of 0.8 it needs to…

### What does unity power factor UPF mean?

Unity power factor has a value of 1.0. This means the current and voltage waveforms are in phase. This is only possible if the net load is non-reactive (resistive). If the load is either capacitively or inductively reactive, the power factor will be other than unity. If an inductively reactive load such as a motor is offset by a capacitively reactive load such as a PF correction capacitor, it is possible to acheive a net…

### How many VA in 1 kilowatt?

In a.c. circuits, the watt is used to measure the true power of a load, and is determined by multiplying the supply voltage by the load current by the power-factor of the load. The volt ampere is used to measure the apparent power of a load, and is determined by multiplying the supply voltage by the load current. So the relationship between the watt and the volt ampere depends on the power factor of the…

### If 2kw generator is supplied to 10 ampere load how much will be its power factor?

The 10 A in the load includes the real power and the reactive power, if it is a single phase 120 V generator it can supply 16.67 A; that means a 2000 KW load at a power factor of 1.00, of for example a 1600 W load at a power factor of 0.80, in both cases the output current of the generator will be 16.67 Ampers, it is the same with the 10 A load…

### 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…
