A novel voltage quality monitoring system

Abstract

With the advent of electricity deregulation, the power quality of electricity supply is getting more and more concern. Customers prefers to have a good electricity supply. In this paper, a novel 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. It is especially useful in applying final circuits for both investigation and monitoring purposes. 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.
