load factor is the ratio of average load to max demand for a given period.
High load factor means
- less cost per KWH
- more efficient use of power plant

Does the power factor in three phase system depend on the phase sequence?
No. It depends on the inductive and capacitive reactance of the load.
What is powerfacter?
The ratio of active power (real power) and apparent power is called power factor ( pf ). Power Factor ( pf ) = Active Power / Apparent Power = .................. ( kvar )
Can power factor be more than one?
No. In the simple case of a linear circuit, the power factor is the cosine of an angle, and that can't be more than 1.
What is the greatest factor of 98x to the seventh power?
The greatest factor of a single term is the term itself.
Power factor is not greater than unity?
Yes. Power factor is never greater than one, nor less than negative one. It is the cosine of the phase angle, and is the ratio of true versus apparent power.A negative power factor can occur in the case of a generator.

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 the importance of ripple factor?
Ripple factor ripple factor is very important in deciding the efficiency of the rectifier .ripple factor give the total power converted AC input to the DC output. Ideal ripple factor should be zero and power factor 1. Ripple factor of half wave rectifier 1.21 and full wave rectifier is 0.48.
Why Voltage x Current do not equal rated power?
In an AC system power is equal to Voltage x Current x Power factor. Power factor is not constant and depends on the type of the load. Ideal value of the Power factor is 1, where as practically remains less then 1.
When induction motors is used for power factor correction what is called?
I'm not sure I've ever seen an induction motor used to correct power factor; it is usually the induction motors that are causing the poor power factor. "Power factor correction" is usually accomplished by adding capacitors to the system to counteract the inductance of large motors.
What components define the system's form factor?
The mother board, power supply, and chassis
