As we know, today in power system, a lot of good equipment dedicated to monitoring power quality of the power supply system specially can provide users with complete data on power quality, and further more, help to improve the level of power quality. And also there are many kinds of devices applied for recording different faults in power system, to help operators generally analysis and determine the fault reason. In a lot of substations, both power quality monitor devices and fault record devices are always existed simultaneously. Maybe they cost a lot of money and seem redundant. With the rapid development of computer technology, many kinds of monitor and analysis devices such as power quality monitor, fault record, phase measurement, and other device can be integrated into one device based on a computer. And it will look very expedient and can do complete all of the work. In this paper, a kind of method to design such multifunctional device will be introduced. And the apparatus we just have developed operates very well in substation. And application results show that this system is very applicable and can be used with great accuracy in dynamic monitoring fault diagnosis and trouble removal.
