The power factor (PF) in any electrical system can be defined as; the ratio of the real power to the apparent power. Here, real power is measured in kW (kilowatts) and apparent power is measured in kVA (kilovolt amperes). So, the power factor is the measure of how efficiently the power is utilized within an electrical system. A low power factor (LPF) means that the electrical system is not completely using the power so that system efficiency can be reduced … [Read more...]
