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 station.

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
What method improve power factor?
The most common method of improving the power factor of a load is to connected a capacitor or capacitor bank, of appropriate reactive power (expressed in reactive volt amperes), in parallel with the load.
Why you install capacitor bank in electrical room?
Capacitor banks are installed in the electrical room to improve the power factor which is related to the inductive load caused by motors etc . The capacitors create a capacitive load which subtracts against the inductive load thereby improving the power factor. Most power utilities have penalties when your power factor drops below a certain value.
What power plant has high load factor?
Diesel Engine has high load factor
What is loss load factor?
A load loss factor, LLF,not loss load factor,Êis a calculation used by electrical utility companies to measure energy loss.Ê Its the ratio of average load loss to peak load loss.
Why the power factor improves with the load?
Power factor doesn't necessarily 'improve with the load', but it is determined by the load.
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.

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.

What is the other name of plant factor in load forecasting?
Load Factor
What is limit load factor in aviation?
the maximum load factor without structural damage to the aircraft. Load factor = 1 / (cos (angle of turn))
What effect a capacitor has on a supply current on an inductive load?
it will improve the power factor... The angle between voltage and current will decrease depends on capacitor value.
Why power factor can not be unity?
Power factor can be unity. If the load is purely resistive, then the load current and supply voltage are in phase, and the load will have unity power factor.
How many load factor equal to 1amp?
Load factor and current are not directly related
What power plant has high load factor?
Diesel Engine has high load factor
