no.... the power factor of any machine should be as near as to 1 when the power factor becomes near to 1 there is no need to the alternator to supply the reactive power.. but in general all most all the loads in the power system inductive in nature the power factor is becoming lagging(<1) so to avoid this the power generating companies and the govt. are recommending the people to have the capacitors at the load ends....... since the capacitive reactance can nullify the effect of the inductive reactance this will try to improve the power factor
What else can I help you with?
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 low power factor watt meter?
A wattmeter reads the true power of a load, regardless of its power factor.
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.
Why transformer power factor taken unity?
It isn't! A transformer operating at no load has a very low power factor.
What mean power factor 0.26 lead?
When looking at power factor, it is the ratio of watts (true power) to VA. The power factor is how we measure power systems. A person with a low power factor like .26 will have a higher electricity bill.
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.
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...
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 are the adverse effects of poor power factor?
Low power factor means higher than necessary load currents. These require unnecessary expenditure on the amount of copper in supply equipment such as cables, transformers, and switchgear. Higher than necessary load currents also mean greater voltage drops and poorer voltage regulation.
Why inductor have low power factor?
An inductor has a low power factor because it is a reactive device, and the phase angle of the current with respect to voltage is not zero. In fact, power factor is the cosine of that phase angle, which means that a power factor of 1 means no phase angle, which means a resistive load. Anything else represents a reactive load and a power factor less than 1.In an ideal case, with perfect inductors and perfect conductors, the power factor would be zero, i.e. the phase angle would be 90 degrees lagging.
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.
