Why ac motor has low power factor?
because of high resistance in the load.
What is low power factor watt meter?
A wattmeter reads the true power of a load, regardless of its power factor.
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...
How does low power factor effects conductor size?
A load with a low power factor draws more load current than necessary, so the supply conductors need to have a greater cross-sectional area than would otherwise be necessary.
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)
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.
What is the main reason for Low Power Factor?
inductive/lagging load
Why ac motor has low power factor?
because of high resistance in the load.
What is low power factor watt meter?
A wattmeter reads the true power of a load, regardless of its power factor.
Why transformer power factor taken unity?
It isn't! A transformer operating at no load has a very low power factor.
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...
How does low power factor effects conductor size?
A load with a low power factor draws more load current than necessary, so the supply conductors need to have a greater cross-sectional area than would otherwise be necessary.
Why you use low power factor wattmeter on primary and unity power factor on secondary side of transformer?
There is no such thing as a 'low power-factor' wattmeter. A wattmeter always reads true power, regardless of the load's power factor.
What is a load electricity wise?
A 'load' is a device that does work by using electricity. 'Load' can also refer to the amount of electricity used.
How do you solve low voltage in electricity problems?
low voltage problem may arise due to unbalancing of distribution transformer in your area. please ask your electricity provider to balance load on distribution transformer.
What has the author Dennis Bellamy written?
Dennis Bellamy has written: 'The domestic consumer' 'Load factor in the electricity supply industry'
What causes low power factor?
Reactive power flow results in a lower power factor. In transmission systems, this can be due to unequal source voltages. In load networks, this is usually due to motor load.
