Method of Measuring Power Quality and Development of Monitor Device project analyzes the main factor in power system which influences power quality, and the necessity of developing monitor device of power quality is analyzed. Measuring method of power quality indexes and the feasibility of monitor device’s realization are also researched. Furthermore, the software is programmed and PS-3 power quality monitor device is developed. The hardware system is composed of industry control computer, data acquisition and analysis module based on 80C198 micro controller and external analog signal transforming box. Every standard of power quality can be tested and analyzed by device developed in this project. At last, the device is used to test the 35 KV bus of a steel factory. The results show that the methods adopted are correct and the precision is higher.  According to the experts, the problems of electric power supply cost the industry and the business community as a whole, 10billion Euros every year.
