Power Factor Correction

Power factor of an AC electrical power system is defined as the ratio of the real power flowing to the load to the apparent power in the circuit, and is a dimensionless number in the closed interval of 0 to 1.

This means low power factor can result in higher reactive current for the same output, which requires larger electrical infrastructure.

If power factor is improved

- The same output can be achieved with relatively smaller electrical infrastructure.

- Electricity bills can be reduced as many utility companies have higher tariff rates if power factor is less than 0.95 .

This electrical calculator is very easy to use and will be useful for people involved in electrical design.
