Research output: Journal article publicationJournal articleAcademic research


In this research, a web-based supply voltage monitoring system based on a compact microprocessor module is presented. It provides a low-cost and flexible solution for monitoring the power quality of electricity supply. The hardware consists of the module and a few extra electronic components. This shortens the development time and lowers the manufacturing cost. Also, the power quality data can be presented via a web page. Any user in the Internet can access the data from the new monitoring system. Moreover, the size of the system is very small presenting no difficulties for installation. All these features make it very competitive to be used as a supply voltage quality monitor. The prototype of this system has been built. It has been applied in our laboratory to continuously monitor the power quality so as to demonstrate its beauty.
