| Abstract: | By taking the Wushan substation which is in Qingdao as an example,the paper discuses the configuration plan,working principles,the optical fiber’s running direction and the synchronous modes of electronic instrument transformers and the merging units（MU）.In addition,an analysis is made of the protecting actions of 220 kV line during operation of the Wushan substation.Finally the effects of non-conventional instrument transformers on the secondary system are summarized.It is concluded that application of non-conventional instrument transformers will bring a change to the operation and management of power grid. |
