An Automatic Power Factor Correction (APFC) Panel is an electrical control system designed to monitor and maintain the power factor of a power distribution network automatically. The power factor is a measure of how efficiently electrical power is converted into useful work output. APFC panels are used to improve power factor by automatically controlling the connection and disconnection of power factor correction capacitors to the electrical system.
The brain of the APFC panel, the controller continuously monitors the power factor and determines the required compensation. It controls the switching of capacitors to achieve the desired power factor.
Capacitor Banks
These are banks of power factor correction capacitors. Capacitors are switched in or out based on the real-time power factor requirements.
Contactors
Electrically controlled switches that connect or disconnect the capacitors from the electrical system. They are controlled by the controller based on the power factor measurement.
Metering and Display
Includes meters and displays to monitor and display important parameters such as power factor, voltage, and current.
Application
01
Commercial and Industrial Installations:
APFC panels are commonly used in commercial buildings and industrial facilities where inductive loads, such as motors and transformers, can lead to a lagging power factor. APFC helps to maintain a more balanced power factor, reducing the overall reactive power demand and improving system efficiency.
02
Power Distribution Networks
APFC panels are installed in electrical distribution networks to ensure optimal power factor correction across various loads.
03
Energy-Intensive Industries
Industries with high power consumption, such as manufacturing and process industries, benefit from APFC panels to avoid penalties associated with poor power factor.
Rating
Voltage Rating
The voltage rating is determined by the system voltage for which the APFC panel is designed.
Capacitor Rating
The capacitors in the APFC panel are rated based on their reactive power capacity and voltage.
Current Rating
The current rating is determined by the load current and the capacity of the APFC panel to handle the connected load.
Advantages
Improved Power Factor
APFC panels help maintain a near-unity power factor by compensating for reactive power, reducing losses in the distribution system.
Energy Savings
Improved power factor results in reduced energy losses, leading to energy savings and increased overall system efficiency.
Reduced Penalties
Many utilities impose penalties on consumers with poor power factors. APFC panels help avoid these penalties by keeping the power factor within acceptable limits.
Extended Equipment Life
APFC contributes to the longevity of electrical equipment by reducing stress on transformers, motors, and other inductive loads.
