Power Factor Correction panels
Automatic Power Factor Correction (APFC) panels are essential components in modern electrical distribution systems, designed to improve the power factor and overall efficiency of the network. The primary function of an APFC panel is to automatically switch capacitor banks into the circuit to compensate for reactive power, thereby reducing the phase difference between voltage and current. By improving the power factor, APFC panels help in minimizing losses, reducing electricity bills, and preventing overloading of the electrical network. This is crucial for industries and commercial establishments where maintaining optimal power quality and efficiency is necessary.
Contactor-based or thyristor-based switching devices are typically used in APFC panels. Contactors are mechanical switches that can quickly connect and disconnect capacitor banks to maintain the desired power factor. Thyristors, on the other hand, are semiconductor devices that provide more precise and faster switching with fewer mechanical parts, which enhances reliability and efficiency. These devices help manage the switching process in a manner that ensures stable and efficient operation, adjusting the power factor dynamically based on the load variations.
