Taking the CSI-200EA measurement and control equipment of a 220 kV substation for example, this paper described the safe measures of the equipment and analyzed the problems discovered in the reforming process of AC circuit, signal circuit, tripping circuit, latch circuit, communication methods and other aspects and gave the corresponding solution. The project result shows that the transformation not only simpliifes the circuit by adding to the essential equipments that are more safe and reliable in operation process; also presents predictabil-ity measures to improve the latter overall communications of the spacer layer and preventive lockout.
