Power Quality Assessment for Industrial Plants: A Comparative Study

Power quality (PQ) assessment has become a major area of interest in recent years because of increased use of sensitive equipments. It is necessary to know the level of disturbances in order to have necessary remedial or preventive measures to avoid equipment malfunction. Power quality surveys play a major role in achieving that. For the study carried out in this paper, power quality monitoring equipments were installed at three industrial sites to record the data. The observed PQ parameters are analyzed, compared and presented in detail. Observed PQ parameters are also compared with relevant standards to understand their severity levels.
