Study and Design of Digital Output Interface on Electronic Transformers According to IEC 60044-8

This paper makes researches on the digital output of electronic current transformers based on IEC60044-8 standard. The structure of electronic transformers, the physi-cal layer, link layer and application layer of digital outputare analyzed in detail. The implementation scheme is pre-sented as well. MU function is achieved in stipulations byadopting DSP as main processor and external circuit, whichcan implement the real time and reliability, and the systemdesign can be expended easily if needed. Finally, the im-pact on substation applying electronic transformers and fu-ture application are discussed.
