Abstract: We are in the need of energy which we have to make major corrections in which the energy is wasted in form of reactive power. So, the required energy is can be utilised in which the energy can have the major correction to form a power factor. The power factor can be developed with the required energy the utilised power is used in a proper way.t\The reactive power can be compensated using capacitor banks and this can be termed as power factor correction. The power factor correction is major problem in a industry to compensate a reactive power factor. The reactive power can be compensated with a reactive and it make into real power. Hence the according to the load the power factor can be compensated using Arduino microcontroller and switching operation is done with the regular power factor and his can be controlled with microcontroller. The microcontroller is programmed with to operate with the necessary coding.

Keywords: Power factor, capacitor bank, solid state relay, precision rectifier, super diode, phase measurement, AC signal measurement, Arduino.
