Power Factor Calculator
Power Factor Calculator: Power Factor (PF) is a measure of how efficiently electrical power is converted into useful work output. It is the ratio of real power (kW) to apparent power (kVA) in a circuit. A high power factor indicates efficient utilization of electrical power, while a low power factor signifies inefficient use, leading to increased energy consumption and costs.
How to Use the Power Factor Calculator
Select the phase type (Single phase or Three phase) from the dropdown. Fill in the required fields such as real power, current, voltage, frequency, and corrected power factor. Click the 'Calculate' button to see the power factor, apparent power, reactive power, and the required capacitance for power factor correction. Clear the fields using the 'Clear' button to start a new calculation.
