摘　　要：三相无功功率变送器按其测量原理划分种类繁多，其中大部分用于不平衡三相电路时存在方法误差，该文从理论上分析推导了这种方法误差的大小，提出了选型建议。Three phase reactive power transducers are divided into various types according to the measuring principle. Most of them exist errors in method in application to unbalanced three phase circuit. This paper analyzes the error and offers a suggestion on selecting types.
