We know that most of the industries and power system loads are inductive that take lagging current which decreases the system power factor, For Power factor improvement purpose, Static capacitors are connected in parallel with those devices which work on low power factor.
These static capacitors provide a leading current that neutralizes (totally or approximately) the lagging inductive component of load thus power factor of the load circuit is improved.
These capacitors are installed in Vicinity of large inductive loads like Induction motors and transformers etc. and improve the load circuit power factor to improve the system or devises efficiency
APFC or Automatic Power Factor Control Panels are mainly used for the improvement of Power Factor. Power Factor can be explained as the ratio of active power to apparent power and it is a key factor in measuring electrical consumption. Everyone knows that how costly electricity has become in the present time. Therefore, it becomes of utmost importance to cut down on electrical consumption for reducing expenditure.
APFC Panels come really handy in the achievement of this purpose Use of these control panels becomes indispensable in those industries where electrical installations are meant to supply to a large electrical load. A dip in Power Factor can attract operational losses and a penalty from the electricity board, responsible for electricity supply.
APFC Panels can effectively and automatically manage quickly changing and scattered loads along with the retention of high-Power Factor. We are renowned manufacturers of APFC Panels symbolized with quality and reliability. These are available in different current ratings to cater to distinct applications. The main features of our control panels are:

Microprocessor-based Power Factor Correction relay controlled the switching of Parallel connected Power capacitor which rated 2.5kVAr, 5kVAr,7.5kVAr,10kVAr,12.5KVAr, 15kVAr,20kVAr, 25kVAr, 50kVAr…and more, corresponding magnetic Contactor for suitable stepping of the capacitor Bank, sometimes also used detuned reactor with series in capacitor for harmonic filtrations
There are many types of Capacitor, Dry type, Gas filed type, Oil-immersed type etc., HRC fuse used in series for protection, sometimes we also use Circuit breaker between Capacitor and Magnetic Contactor for protection and easy operation
BENEFITS OF INSTALLATION APFC PANELS
There are numerous benefits to be gained through power factor correction. These benefits range from reduced demand charges on your power system to increased load carrying capabilities in your existing circuits and overall reduced power system losses. And the benefits of power factor correction aren’t just limited to the balance sheet; there are also huge environmental benefits associated with power factor correction, which means your company is reducing its carbon footprint and helping the environment.
REDUCED DEMAND CHARGES
Most electric utility companies charge for maximum metered demand based on either the highest registered demand in kilowatts (KW meter) or a percentage of the highest registered demand in KVA (KVA meter), whichever is greater. If the power factor is low, the percentage of the measured KVA will be significantly greater than the KW demand. Improving the power factor through power factor correction will therefore lower the demand charge, helping to reduce your electricity bill.
INCREASED LOAD CARRYING CAPABILITIES IN EXISTING CIRCUITS
Loads drawing reactive power also demand reactive current. Installing power factor correction capacitors at the end of existing circuits near the inductive loads reduces the current carried by each circuit. The reduction in current flow resulting from improved power factor may allow the circuit to carry new loads, saving the cost of upgrading the distribution network when extra capacity is required for additional machinery or equipment, saving your company thousands of dollars in unnecessary upgrade costs. In addition, the reduced current flow reduces resistive losses in the circuit.
A lower power factor causes a higher current flow for a given load. As the line current increases, the voltage drop in the conductor increases, which may result in a lower voltage at the equipment. With an improved power factor, the voltage drop in the conductor is reduced, improving the voltage at the equipment.
REDUCED POWER SYSTEM LOSSES
Although the financial return from conductor loss reduction alone is seldom sufficient to justify the installation of capacitors, it is sometimes an attractive additional benefit; especially in older plants with long feeders or in field pumping operations. System conductor losses are proportional to the current squared and, since the current is reduced in direct proportion to the power factor improvement, the losses are inversely proportional to the square of the power factor.
REDUCED CARBON FOOTPRINT
By reducing your power system’s demand charge through power factor correction, your company is putting less strain on the electricity grid, therefore reducing its carbon footprint. Over time, this lowered demand on the electricity grid can account for hundreds of tons of reduced carbon production, all thanks to the improvement of your power system’s electrical efficiency via power factor correction
