APFC Panel stands for Automatic Power Factor Correction Panel. It is an electrical control panel used to improve the power factor of electrical systems in industrial and commercial settings. Power factor is the ratio of real power (kW) to apparent power (kVA) in an electrical system. A low power factor can result in inefficient energy usage and higher electricity bills. The APFC Panel automatically monitors the power factor and makes necessary adjustments to improve it. Here’s a detailed description of APFC Panels:

1. Purpose: The primary purpose of an APFC Panel is to maintain a near-unity power factor by automatically controlling the reactive power (kVAR) in the electrical system. By correcting the power factor, the panel ensures efficient power utilization, reduces line losses, and optimizes energy consumption.
2. Capacitor Banks: APFC Panels typically consist of capacitor banks, which are made up of capacitors connected in parallel. These capacitors help in the compensation of reactive power, leading to a higher power factor.
3. Reactive Power Compensation: The APFC Panel continuously monitors the power factor of the electrical system. If it detects a low power factor, it automatically switches on the required capacitors from the capacitor bank to provide the necessary reactive power. Similarly, if the power factor is too high, it switches off some capacitors to avoid over-correction.
