In industry most of the load is inductive in nature which results in lagging power factor that is why there is loss and wastage of energy which results in high power bills and heavy penalties from electricity boards. If the load is uneven it is very difficult to maintain unity power factor. To overcome this difficulty APFC panel is used which maintains unity P.F.

With an APFC the energy producer can:

• Avoid Penalization for lower power factor.
• Enjoy incentives for higher power factor operation being extended to Industries by some   Electricity Boards/ Companies.
• Optimize the connected load for improved plant load factor.
• Avoid manual disruption.
• Avoid high current consumption losses.
• Improvement in voltage regulation.
• Decrease Maximum Demand KVA, thus avoiding penalty and Demand Charges.

APFC Panels


Reasons why APFC Panels are needed :

An Automatic Power Factor Correction (Controller) panel or in short APFC Panel is used to Save Energy by consistently maintaining higher power factor. Low Power Factor leads to poor power efficiency, thereby increasing the apparent power drawn from the distribution network. This result in overloading of Transformer, Bus bars, Switch gears, Cables and other distribution devices within the Industry or consumer area.

Features And Applications :

High speed power factor correcting system are designed to compensate the reactive power of any load or equipment requireing P.F. correction within a one cycle of opearating frequency or time delay of 30 sec to 5 min after command signal from APFC controller.

Renders the distribution network more stable since there is no contactor switching causing high voltage transients, spikes, harmonics and other disturbances by applying zero cross over voltage switching ON and zero current switch OFF of the capacitors.

Prevents voltage drop and fickering reduces failures in highly sophisticated electronic equipments like PLCs, computers and other control systems.

Helps in reducing maximum demand and RKVAH consumption hence substantial reduction in monthly electricity triff.

It is highly suitable for spot welding applications where the reactive energy is to be compensated for a short period of 200 msec or less and for a number of times in a second.

Accurate power factor control even in the presence of harmonics.

Applications :

Textile Machineries
Printing Industry
Pharmaceutical Industry
CNC Machine
Hospitals
Film Industry
Food Processing industry
Resorts
Hostels
Farm house
Engineering Plant
Automobile Industry
IT industry
