This calculator helps electrical engineers and technicians optimize power systems by calculating the necessary power factor correction. Enter your parameters to get started.
All calculations are rigorously based on the formulas provided in the IEEE Std 141-1993. All calculations rely strictly on these authoritative sources.
Required Capacitor (kVAR) = Load (kW) × (tan(acos(Current PF)) - tan(acos(Desired PF)))
Current Power Factor: The existing power factor of your system.
Desired Power Factor: The power factor you wish to achieve for optimal efficiency.
Load (kW): The power demand of your system in kilowatts.
Required Capacitor (kVAR): The size of the capacitor needed to achieve the desired power factor.
Power factor is a measure of how effectively electrical power is being used. A higher power factor indicates efficient utilization of electrical power.
Correcting the power factor can reduce electricity costs, improve voltage regulation, and increase the capacity of your power system.
The required capacitor size is calculated using the difference between the tangent of the angles of the current and desired power factors.
