Frequently Asked Questions
Power factor is the ratio of real power (P) to apparent power (S) in an AC circuit, ranging from 0 to 1. It indicates how effectively electrical power is being used.
Improving power factor reduces reactive power, lowers electricity bills, increases system capacity, and reduces line losses. Utilities often charge penalties for low power factor.
Select the system type (single or three-phase) and the known values you have. Enter the required values and optionally a target power factor and frequency to get the capacitor bank size.
