An APFC (Automatic Power Factor Correction) panel with a contactor switch is used to improve the power factor in electrical systems automatically. It does this by switching capacitor banks in and out of the circuit using contactors, based on the system's real-time reactive power demand.

1. Power Factor Controller

   • The brain of the panel. It measures the power factor and controls the switching of capacitors.

2. Contactor Switches

   • Electromechanical switches that connect/disconnect capacitor banks based on the controller's signal.

3. Capacitor Banks

   • Provide reactive power compensation. These are connected in steps (e.g., 5kVAR, 10kVAR, etc.).

4. MCBs/MCCBs/Fuses

   • For protection of individual capacitor stages.

5. Detuned Reactors (optional)

   • Used in harmonic-rich environments to prevent resonance and damage to capacitors.

6. Busbars, Cables, and Wiring

   • For power distribution within the panel.

7. Indicators, Meters, and Alarms

   • For monitoring voltage, current, PF, and alarms in case of failures.

• The controller continuously monitors the power factor of the system.

• When the PF drops below a set threshold (e.g., 0.95 lag), the controller activates contactors to switch in capacitor banks.

• As PF improves or demand changes, the controller will deactivate certain stages, ensuring optimal compensation.

• This entire process is automatic and helps in reducing penalties for low power factor, improving system efficiency, and extending equipment life.

• Purpose:PFC panels are used to improve the power factor, which is the ratio of active power (watts) to apparent power (volt-amperes). A low power factor means that a significant portion of the electricity is not being used to do work, leading to wasted energy and increased costs. 
• How it works:PFC panels typically consist of a microcontroller-based controller, capacitors, and other electrical components. The controller monitors the power factor and automatically switches capacitor banks on or off to compensate for reactive power fluctuations. 
• Benefits:By maintaining a high power factor (close to 1), PFC panels help to:
  • Reduce power losses and improve energy efficiency. 
  • Lower electricity bills by reducing reactive power consumption. 
  • Reduce voltage drops and improve voltage stability. 
  • Avoid power factor penalties imposed by utility companies. 
  • Increase the lifespan of electrical equipment. 

• What is Power Factor?Power factor is the ratio of real power (used to do work) to apparent power (total power supplied). A poor power factor (below 0.9 or 0.95) means a significant portion of the supplied power is wasted, leading to higher electricity bills and inefficiencies. 
• Why is APFC Needed?Many electrical loads, particularly inductive ones like motors and transformers, consume reactive power, which doesn't contribute to actual work but creates a lag in the system. APFC panels counteract this by supplying reactive power using capacitor banks, thus improving the power factor. 
• How it Works:The APFC panel monitors the power factor of the system. When the power factor drops below a set threshold, it automatically switches on the necessary capacitor bank units. These capacitors provide the reactive power needed to counteract the inductive load and improve the power factor. 
• Benefits of Using APFC Panels:
  • Improved Power Factor: Reduces wasted power and improves energy efficiency. 
  • Reduced Electricity Costs: Lower energy bills due to better power factor. 
  • Voltage Stability: Helps to maintain a stable voltage level in the system. 
  • Extended Equipment Life: Reduces stress on equipment due to improved power factor. 
  • Compliance with Utility Regulations: Many utilities require a minimum power factor level and may penalize customers with poor power factors. 

• Power Factor Improvement:APFC panels monitor the power factor of the electrical system and automatically switch on or off capacitor banks to compensate for the reactive power needed by inductive loads, like motors,. 
• Reactive Power Control:By controlling the reactive power, APFC panels help maintain the power factor close to unity (1), which is the ideal power factor. 
• Reduced Electricity Bills:A higher power factor means less apparent power is drawn from the distribution network, leading to lower electricity costs and reduced power loss. 
• Improved Voltage Stability:By managing reactive power, APFC panels help reduce voltage drops and improve voltage stability in the system. 

• Capacitor Banks:These are the main components that store and release reactive power as needed. 
• Power Factor Controller:A device that monitors the power factor and controls the switching of capacitor banks, often using a microcontroller or relay,. 
• Switchgears:These are the electrical components that switch the capacitor banks on or off,. 
• Meters:Instruments to measure various electrical parameters like power factor, voltage, and current,. 

• Power Factor:Power factor is the ratio of active power (the actual power used) to apparent power (the total power supplied). A low power factor means more apparent power is being supplied than is actually being used, resulting in energy wastage. 
• APFC Function:APFC panels monitor the power factor of an electrical system and automatically switch capacitor banks on or off to correct the power factor. Capacitors are used to counteract the lagging reactive power caused by inductive loads, like motors and transformers, improving power factor efficiency.
