Poor power qualities affect functioning of utilities, different industrial units, productions, customer services and other system performance and operating costs. There is an ever increasing need for power quality monitoring systems due to the growing number of sources of disturbances in AC power systems. Monitoring of power quality is essential to maintain proper functioning of utilities, customer services and equipments. The authors surveyed different existing methods of power quality monitoring already in use and available in literature and arrived at the conclusion that an improved and affordable power quality monitoring system is the need of the hour. This paper gives the initial part of the research works of the authors leading to the development of a simple power quality monitoring system by designing virtual instruments using LabVIEW software. The system is suitable for utilities and end-users. The tests were carried out in the research laboratory and the control panel of the Electrical Engineering Department, Aligarh Muslim University, Aligarh (India), supplying a large number of PCs, electronic equipments, high power UPS and electrical machines. Observations of the system depict the importance of power quality monitoring, and also the accuracy and the precision of the developed system.
