    Arduino Based Automatic Power Factor Control
    (INTERNATIONAL JOURNAL of SMART GRID, 2021) Al Rakib, Md Abdullah; Nazmi, Sumaiya; Imam, Md Hasan; Nasir Uddin, Mohammad
    - When the inductive load is brought into the industry, it is known that the power factor will drop. The electricity cost will be greater if the power factor is decreased. When the power factor drops in our system, the automated capacitor sets are activated, and the factor of power is restored with a predetermined level. The unique element of our research work is that an IoT (Internet of Things) technology was used to complete it. It will be capable to monitor and operate the research work from any place on the Internet, in addition to monitoring from the research work display. As a programming device, it has been utilized an Arduino Uno Microcontroller. The PF may be improved to increase current-carrying capacity, enhance voltage to equipment, minimize power losses, and cut electric costs. Reactive current generators are PF correction capacitors. We contribute to increasing the power factor by helping to balance the nonworking power used by inductive loads. In this article, the power factor of a load is measured using an Arduino Uno microcontroller, in which the necessary capacitors are then triggered to compensate for reactive power and put the factor of power closer near unity.
