Abstract - The project is designed to minimize penalties by using an automatic power factor correction unit with the help of Raspberry Pi. The power factor is defined as the ratio of real power to apparent power. This definition 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 nonworking power but 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 a low power factor, the industry needs more energy to meet its demand, so the efficiency decreases. Therefore, it can be seen that reducing the total current to the actual current required would result in greater efficiency. Power Factor values are in the range of 0- 1, hence an electrical system with a power factor of 1 (unity) is using 100% useful current with no inefficiency. However, an electrical system with a power factor of 0.5 (50%) is using twice as much current as it needs. This technique can be applied to industries, power systems, and also households to make them stable, and due to that the system becomes stable and the efficiency of the system as well as the apparatus increases.
