Development and analyse of Electronic Transformers

Electronic Transformers (ECT, EVT)are a sort of sensors of reactive agents in the reactive layer of the Strategic Power Infrastructure Defense system, are sense organs of the SPID in the Smart Grid, are a sort of key devices for the Smart Grid. The past Electromagnetic Transformers can not satisfy desire. With rapid development of the fiber and sensor technique, the technology based on fiber isolation and transmission is more mellow and perfect. This paper expounds development and sorts of Electronic Transformers, analyses the characteristic and engineering application instance between two kinds of Electronic Transformers, points out the problem in Electronic Transformers production, bring forward the development direction and regarded problem of Electronic Transformers research.
