Abstract In view of the difficulties in the measurement of the current series compensation system, the interference sources and interference paths of the current transformer measurement system on the series compensation platform are analyzed. This paper introduces the realization of relevant functional modules of centralized electronic TA measurement system, and designs a centralized electronic TA measurement system. The reliability of the system is improved by using the full laser power supply technology with redundant closed loop control and the design of centralized measurement unit, and the application in practical engineering is realized.
