Power factor is defined increase as the ratio of real power to apparent power. Where real power is the time integral of the instantaneous power measured over a full period and the apparent power is simply the product of the RMS voltage and RMS current measured over the entire period. The time lag between the zero voltage pulse and zero current pulse duly generated by suitable operational dual amplifier circuits are fed to two interrupted a pins of the microcontroller where the program takes over to actuate appropriate number of relays at its output for bringing shunt capacitors into the load circuit to get the power factor till it reaches 0.97. Shunt capacitor ratio will be change a current and voltage due to the power efficiency define and power its changed a circuit power due to high and current. Measure a unit pulse count and current transformer due to show the rating and increasing power factor value will be change show the display which device perform like “LED BULB, BULB,MOTOR,AC,TV,REF,” all using this technique power factor increasing due to easily saving energy of a Power.

INRTODUCTION This thesis presents the design and implementation of designed to reduce the power loss in industries by power factor compensation through a number of shunt capacitors. This results in reduction in amount of electrical load for industries and commercial establishments. Power factor increase is a defined as the ratio of Real power to apparent power. This principal at a is often mathematically represented as KW/KVA, where the numerator is the active (real) power and the denominator is the (active + reactive) or apparent power. Reactive power is the non-working power generated by the magnetic and inductive loads, to generate magnetic flux. The increase in reactive power increases the apparent power, so the power factor also decreases. Having low power factor, the industry needs more energy to meet its demand, so the efficiency decreases. This implemented design will help at utility to improve fault restoration time and we can utilize transformers for long period of time. Transformers electric device are step-down power system components which are used at various voltage levels with the capacity varying from 1KVA to 600MVA. Any damage to this component results is completely loss in power system. Having low power factor, the industry needs more energy to meet its demand, so the efficiency decreases. In this technique for system the time lag between the zero voltage pulse and zero current pulse duly generated by suitable dual operational amplifier circuits in comparator mode are fed to two interrupt pins of the microcontroller. Microcontroller atmega 328 and capacitor charge due to start system and relay protection is on displays the power loss due to the inductive load on the LCD 16x2. The program takes over to actuate appropriate number of relays at its output to bring shunt capacitors into the load circuit to get zero power loss In Electronics power unit system, a monitor to fault condition is any work to flow condition of electric current. As like a short condition circuit break is a transformer fault in which current flow by passes through the
