A web-based distributed measurement system for electrical Power Quality monitoring

Industries´ systems are shifting toward almost entirely sophisticated electronic devices. Power Quality (PQ) analysis is getting importance for the economy because this equipment is highly sensitive to PQ events. Control and supervision of an industrial process has mainly been focused on the electrical protection, and little attention has been paid to the quality of the electrical supplies. Nowadays, measurement and communications systems have advanced to enable the installation of web-based sensors within a PQ assessment scenario. In this sense, this paper presents an innovative low-cost measurement system, as well as investigates the challenges and trends in the development of distributed PQ measurement systems using smart sensors.
