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.

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.
Causes of low power factor methods of improving power factor?
using highly inductive loads may lead to reduction in the power factor. or consumption of unappreciable amount of power also results in the same. methods to improve PF . using synchronous condensers using capacitor banks using ow inductive loads
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 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 causes Isuzu trooper not to have power to ignition?
low or no oil pressure
Why ac motor has low power factor?
because of high resistance in the load.
What causes air in power steering?
Air in a power steering system is caused by low fluid or a leaking seal. When the fluid is low, the pump becomes exposed to the air and causes large bubbles to form.
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.
