Abstract: Industries facing problem of low power factor (P.F) is very common and so are the efforts at improving it through various methods. In general shunt capacitor banks are used to improve the power factor and these banks are located very near and down the final transformer. Attempts will be to maintain the P.F as close to unity as possible. Switching operation of capacitors in a P.F control panel can be achieved by the micro-controller. But it may be very involved and difficult task to write and achieve a running and successful programme on micro-controller for all the power factor values in demand from the same panel. In this work the design procedure of a programme usable in a micro-controller is shown. This is achieved in/and through a lab tool of simulation and can be done also through similar tools. P.F control devices doing switching operation of capacitors can also be used. But they have associated complexity, extra cost, extra efforts at design and finally limitations imposed by the device in power handling. Hence, the present choice of avoiding P.F Controller may be better. The implicit instructions derived from the use of the lab tool implemented as required through the use of this programme can simplify and be extended easily to wide ranges of power handling leading to energy savings.
