|Reasons why APFC Panels are needed :|
|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.|
|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.
For maintaining the power factor according to the load factor, proper capacity of capacitors is to be connected. The value of capacitors to be connected will vary with respect to load and its existing PF. There are two ways to maintain PF-
