Power factor (pf) is the ratio of real power to apparent power in an electrical system.

• Power factor is a measure of how effectively electrical power is being used in a system.

• It is calculated by dividing the real power (in watts) by the apparent power (in volt-amperes).

• A power factor of 1 indicates all the power is being used effectively, while a lower power factor means some power is being wasted.

Harmonics are multiples of the fundamental frequency in a waveform, causing distortion in electrical systems.

• Harmonics are caused by non-linear loads in electrical systems.

• They can lead to overheating of equipment and increased energy consumption.

• Common sources of harmonics include variable frequency drives and power converters.
