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.
