It helps to understand the behavior of the electrical system. Normally if rating of a device say a motor is 11 KW, it is not necessary that it consumes 11 kw all the time. The loading conditions may vary during its running.

What are the advantages and disadvantages of unity power factor?
There is no disadvantage of unity power factor, because at unity power factor all the electrical power is efficiently utilized by the the load, and at lagging power factor some power is lost in the load's magneticfield.
What does a load do to the flow of electrical current in a series circuit?
A load increases the flow of electrical current in a series circuit. No load, no flow.
What is limit load factor in aviation?
the maximum load factor without structural damage to the aircraft. Load factor = 1 / (cos (angle of turn))
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.
Can you run electrical wire's in load bearing wall?
Yes, you can run electrical wires in a load bearing wall.
What is the average electrical load factor of an industrial facility?
50%
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.
What are the advantages and disadvantages of unity power factor?
There is no disadvantage of unity power factor, because at unity power factor all the electrical power is efficiently utilized by the the load, and at lagging power factor some power is lost in the load's magneticfield.
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.
How we calculate load of electrical instrument?
I am not an electrical guy....but since this question was left unanswered....i'll just put in some nonsense!! For AC Load: VxIxPF (V=VoltageRequired, I=Current Required, PF=Power Factor) The Power Factor is normally considered to be 0.8 as a thumb rule. For DC Load: VxI, here the power factor is consisdered to be 1, since it is a DC current !! Byeee!
What significance has a power factor in an unbalanced system?
A three-phase 'unbalanced' system refers to the load, as the supply voltages are unaffected by load. So the phase-angle and, therefore, the power factor of each phase will be different -i.e. there will be three different power factors.
What is a real life application of the square root function?
Electrical engineers use it in calculating power factor and electrical load distribution when dealing with 3 phase power connections.
What is An electrical load is?
Load is simply any thing which dissipate electrical energy.
What is the meaning of 'plant 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)
What is the other name of plant factor in load forecasting?
Load Factor
Why the power factor improves with the load?
Power factor doesn't necessarily 'improve with the load', but it is determined by the load.
What does a load do to the flow of electrical current in a series circuit?
A load increases the flow of electrical current in a series circuit. No load, no flow.
