The Application of Electronic Transformers in Digital Substation

The new electronic transformer is expounded here about its standard,definition,frame,performance,and routine test,the compare of electronic transformer with routine transformer shows that electronic transformer has obvious advantages such as good insulation,good transient performance,high security,small solidity,and low price. The currently main types of electronic transformers inland and overseas are described here,the virtues and disadvantages of them in application are also described,it is pointed that the electronic transformer with electricity theory can satisfy the need of practice. The principle and scheme of electronic transformer application in digital substation are analyzed here,it is pointed that for automatization of substation,especially for EHV and UHV substation,application of electronic transformer will leads deep effect and revolution,which have very important technical and economic significance.
