Automatic Power Factor Corrector and Monitor Device

Microcontroller-based system that monitors AC load and automatically switches capacitor banks to correct the power factor.

Automatic Power Factor Corrector and Monitor Device

Overview

A device that continuously samples voltage and current of an AC line, computes the displacement angle and switches in capacitor banks via relays to bring the power factor close to unity. The on-board display shows real-time voltage, current, true/apparent power and power factor.
