Why a rotor of an alternator at rated power dissipates more heat at a low power factor load than at a high power factor load?
at lower power factor current drawn by load is high and at higher pf the current drawn is less...
Why ac motor has low power factor?
because of high resistance in the load.
How improve load factor?
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.
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)
How you improve power factor in synchronous motor?
Power Factor measures the difference in phase between the current and voltage. When they are in phase the Power Factor is defined as 1. When out of phase the value is less than 1. If they are 180 degrees out of phase the Power Factor will be zero.

What is the importance of load factor in power system planning?
load factor is the ratio of average load to max demand for a given period.High load factor meansless cost per KWHmore efficient use of power plant
Does low load in transformer lead to low power factor?
Power factor is determined by the nature (resistive, inductive, capacitive) of a load, not whether it is a low load or a high load.
How do you calculate the plant load factor of hydro electric power plant?
PLF of Hydal Plant - 100% or 101%
How is plant load factor in solar power plants?
Plant load is a factor in every energy plant. In the case of solar power plants, the plant load factor is at an average of 75%. This means 25% of the time, optimum operation is not utilized. This number has to be compared with start up costs, operating costs and income generated to determine the feasibility of conversion to solar energy.
What is the other name of plant factor in load forecasting?
Load Factor
Why ac motor has low power factor?
because of high resistance in the load.
Why the power factor improves with the load?
Power factor doesn't necessarily 'improve with the load', but it is determined by the load.
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 do you convert power load to VA?
Divide Power Load by "Power Factor"
