AUTOMATIC POWER FACTOR CORRECTION USING ARDUINO

In this Industrial age as wastage of power is a global concern, efficient generation of power is crucial task. These days many industries in the country face monetary losses and electrical burden which are inductive in nature and therefore causing slacking power factor. The Purpose of this project is to present a simple and economical design of an Automatic power factor correction for single phase loads. This system uses relay to switch the capacitor banks in order to correct the power factor of lagging loads. The switching operation of relay is controlled by Arduino. Arduino is programmed in such a way that it can monitor the system and calculate the power factor of the loads by sensing the signals from Current Transformer, Potential Transformer and keep the power factor above 0.9 by energizing the capacitors in parallel to the connected load by Relay switching.
