Power Factor Correction Capacitors Theory & Applications
How does Power Factor work?

Introduction:
The vast majority of plant loads are inductive and need a magnetic field
to function: Transformers, fluorescent lighting, and motors
Although necessary, the magnetic field doesn't actually do any
work.
The utility must provide both the active power (P), which does useful
work, and the reactive power (Q), which creates the magnetic field. You
are responsible for paying for everything.
You pay for "P" through power consumption, and you pay for "Q" through a
penalty for poor power factor.
The active and reactive components are these two categories of
current.
Definition of power factor
The active power to apparent power ratio of a load yields the power
factor for that load.
i.e., the ratio of KW to KVA at any given time.
What we shall discover is that most industrial loads need both reactive
and actual power to function well.
You must pay for BOTH active and apparent power (low power factor penalty
for apparent power).
instances 1 and 2
The REACTIVE power does not need to be supplied by the utility because
capacitors can supply it.
Your money is saved through capacitors!
