Abstract:The use of electrical transducers provides new opportunity and solve some difficult problems of protective relay such as the current transducer saturation and lower transient precision. For conform this new development, according to the IEC60044-8 standard of electronic transducers and IEC61850 standard of communication networks and systems in substations, this paper designs the interface scheme between the OCT and protection devices, and introduces the hardware construction and software flow. The interface scheme has tested by using testing software. The result indicates that interface scheme has good function of communication between the electrical transducer and protective relay devices.
Keywords:electrical instrument transducer  relay protection  digital interface
