Multi-Variable Criteria-Based Optimization of Watt Meters

Ordu, Eze Sunday Jackson, Ojuka, Otonye Ene

Abstract


This study concentrated on optimizing watt meter performance by examining the effects of electrical variables, environmental variables, and load-related variables on watt meter accuracy acceptability. Watt meters play an important role in ensuring efficient and reliable operation of electrical systems, but their performance can be impacted by various factors, including current and voltage levels, ambient temperature, electromagnetic interference, voltage fluctuations, current harmonics, frequency variations, and load characteristics. Our results show that the watt meter's accuracy performance varies across different frequencies, with average percentage errors ranging from 0.73% to 2.13% for 100W and 200W power levels. The watt meter's accuracy is sensitive to frequency changes, specifically at higher power levels, with percentage errors increasing by up to 1.7% for 200W at 60Hz. These findings focus on the importance of reflecting these factors in the selection, calibration, and operation of watt meters to ensure accurate power measurement and optimize electrical system performance. By knowing the factors that affect watt meter accuracy, measures can be taken to minimize errors and ensure reliable power measurements, ultimately adding to the efficient operation of electrical systems.
