This document summarizes a research paper that presents a low-cost hardware system to detect and measure common power quality parameters. The system uses a PIC microcontroller to sense voltage from the power system and detect issues like sags, swells, harmonics, fluctuations and more. When problems are detected, the microcontroller outputs information to an LCD display and LED indicators. The system is designed to be simple, secure and inexpensive while helping minimize equipment failures and losses from power quality issues.
