摘要：
To deal with the problem that one Power Quality Analyzer can only monitor one group of three-phase voltage and current signals, we proposed two different control circuits based on one kinds of Power Quality Analyzer designed by IEC-61000-4-30 standard that can make one Power Quality Analyze monitor Multiple signals. Then we compared characters of two different control circuits that one based on time relay and another based on MCU. After that we choose time relay circuit as our best choice and its record data in actual monitoring was analyzed.
