APFC Control Panel
APFC Panel has microcontroller based programmable controller which switches the capacitor banks of suitable capacity automatically in multiple stages by directly reading the reactive load (RKVA) which works in the principle of VAR sensing tends to maintain the PF to 0.99 Lag.
The capacitor banks may be selected in number of stages as 4/6/8 according to the load pattern. Modern power networks consists of wide variety of electrical and power electronics loads, in case of such varying loads, the power factor also varies as a function of the load requirements .
So it is practically difficult to maintain consistent power factor by the use of fixed compensation i.e. fixed capacitors which shall need to be manually switched to suit the variations of the load.
Install APFC Panel to avoid penalties and enjoy the benefits automatically. 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-Fixing of capacitor at the load end permanently or at the mains. Generally which is recommended for the fixed load like pumps, fans etc. and it is not possible for the load which has variations in the load and PF.
