Automatic Power Factor Controller Panel

Automatic Power Factor Controller Panel


An automatic power factor controller (APFC) system is a necessity in view of high cost of power as well as stiff penalties imposed against low power factor, which leads to poor power efficiency, thereby increasing the apparent power drawn from the distribution network. This results in overloading of transformer, bus bars, switchgear, cables and other distribution devices within the industry or consumer area. Servomax APFC system ensures optimum power for the running loads. The present day electrical networks cater to a variety of non linear loads (like UPS, soft starter, VFD, etc), which dynamically fluctuate and create waveform distortion thereby necessitating installation of APFC panel with line filter. This is necessary in order to: avoid penalty for lower power factor; enjoy incentives for higher power factor operation being extended to industries by some electricity boards/companies; optimise connected load for improved plant load factor; avoid manual disruption; avoid high current consumption losses; improvement in voltage regulation; and decrease maximum demand kVA, thus avoiding penalty and demand charges. Additional advantages of operating the entire factory with APFC panels are: minimising the line losses, thus saving power consumption; longer life for all electrical circuits, cables, bus bars, switches, motors, etc; decrease in the downtime and enhanced performance of the connected equipments; curtailment of leading power factor; reduction of current consumption charges; accelerated depreciation can be availed in the first year itself; and modular design for easy installation, operation and maintenance.
