APFC Panels ^
APFC Panel is a cost effective solution to improve the Power Factor in any industry. It automatically switches ON and OFF the required amount of Capacitors depending upon the load variation to achieve the set PF. The APFC Panel is a perfect solution to manage Power Factor and to improve the life of the Capacitors. It has a fantastic payback period. It has necessary Switchgears, Contactors, Isolating switches, HRC fuses and an Intelligent Micro Processor based Power Factor Controller. This can be used for switching externally/internally installed Capacitor banks for integrated management of load Power.
MELCON APFC Panel has many advantages compared to other competitors because of its intelligent unique design of the banking pattern that helps to improve the desired Power Factor for all kind of loads. A load & therefore its KVAR are in a dynamic state - generally. A matching KVAR output of a capacitor bank must also be dynamic i.e. must adjust itself-instantly to its requirement, if one is to obtain a uniform &'set' p.f. all along. This is best achieved by an automatic control that switches in & out, segments of a designed capacitor bank. A control panel serving this purpose is called on APFC panel or Automatic Power Factor Controlling panel. It controls the load power factor by sensing various available parameters. Structural Design of an APFC Panel 1) Capacitor bank step (section) 2) Discharge resistance on individual capacitor unit - external 3) Incoming switch fuse for the bank 4) Capacitor bank bus bar 5) Capacitor bank CT's 6) Ammeter selector switch 7) Ammeter for bank current 8) Thermal overload relay or sectional fuses 9) Automatic control relay & p.f. meter.

Increasingly, Indian Industry is paying one of the highest power tariffs in the world.
Countries in this club such as Germany and Italy have benefited from Automatic Power Factor control as a competitive edge. They are already global leaders in Automatic Power Factor Compensation (APFC) Capacitors and Panels.
Energy Efficiency, the Competitive Edge [Get Quote]
The demand for energy is projected to grow twice as fast in Asia as for the rest of the world over the next 20 years. India is projected to claim a significant portion of this Asian demand. However, with a smaller reserve of resources, Electricity prices in Asian Countries are already some of the highest in the world. The per-unit cost in India is almost twice that in Canada. With increasing global competition, countries with higher electricity costs can benefit significantly from improvements in Energy Efficiency. Further, improvements in energy efficiency are already proven to have the fastest payback, compared to improving availability through Generation.
Power Factor (PF) improvement is therefore one of the fastest ways to a better bottom-line.
The Principle of PF Compensation ^ While the ideal Power Factor (PF) is Unity or 1, most Industrial loads have a PF lower than 1. Moreover, this lower PF is usually Inductive, arising out of the windings of Transformers, Motors, and the like. These loads consume kVARs (the Wattless component) from the supply line. The principle of PF Compensation is to supply these kVARs via a capacitor located close to the load, reducing the current drawn from the supply line.
Automatic PF Compensation For an Industry with dynamically changing loads, Automatic PF Compensation affords the best Return on Investment, since the kVAR investment required is smaller than with fixed capacitors needed to meet the entire load. Automatic PF Correction also avoids Leading PF situations by switching off extra capacitors.
Products
Power factor Correction is achieved now a days by installing power
capacitors . Under fixed load conditions it is possible to put power
capacitors in the system which will compensate completely for the
wattles component and power factor can be improved to its maximum
value. This obviously will not be an exact compensation for loads
which are varying in value quite frequently. Power factor can be controlled manually or by automatic control systems.
In manual control the operator has to go on making adjustment all the time, which is very tricky and human error cannot be ruled out.
In automatic control, power factor control relay keeps on sensing the power factor all the time and gives suitable signals to contactors connected to it to energize required capacitors. ^
