| Abstract: | The paper researched on the isoelectric point setting based on independent CT. Through analyzing the normal 500kV 3/2connection mode and the 220kV double buses-connection mode for the isoelectric point setting for current transformer, the paper compared the harm of the fault and derives the correct connection mode. In view of wrong isoelectric point setting, the paper proposed the regulation plan. |
