The power
factor of an electrical supply is the ratio of the real power to
the apparent
power of the supply. It is the useful power used by the load divided by the
total power that is drawn. The latter includes power that is unusable, so a power
factor of 1 is desirable. A low power factor would mean that the electricity
supplier would effectively supply more energy than the consumer’s bill would
indicate, and suppliers are allowed to charge for low power factors.
UNDERSTANDING POWER
FACTOR
Power Factor (PF by definition is the ration of real power to apparent
power
Power Factor = Real Power (Watts) / Apparent Power (VA)
People generally convert watts to VA (Watts = VA), which is not true unless
the Power Factor of a system is 1, for the purely resistive circuit- for
example, an incandescent light bulb-the power factor is 1 because the reactive
power equals to zero.
Power factor can be an important aspect to consider in an AC circuit,
because any power factor less than 1 means that the circuit’s wiring has to
carry more current than what would be necessary to deliver the same amount of
(true) power.
Let's consider two examples with
the following characteristics.
Power of Motor = 2KW, V = 250V, Current = 12 Amp.
Power Factor Calculation is as
follows
Power Factor = 2000/(250x12)
= 0.67
Now we consider the another case
in which we will stabilize the voltage at 230V through servo voltage stabilizer
Power Factor = 2000/ (230x12)
= 0.72
From above, it is clear that with the voltage optimization we can improve the
power factor which are directly affect our system and gives us a huge power
saving as well as also prevent us from penalty i.e imposed by utilities due to
poor power factor. Further now a day’s utilities are adhering the tariff plan
on KVAH basis so improving the power factor by using servo voltage stabilizer
we can also reduce our energy bills.
So it can be concluded that servo voltage
stabilizer are multipurpose equipment which can provide the optimum voltage as
well as also serves as a power factor correction equipment which will helps us
in improving the power factor, So power factor improvement will be an
additional benefit of servo voltage stabilizer which will reduce our electricity
charges and also enable us to serve the nation through energy optimization.
