電力系統逐漸向超高壓、大容量和數位化的方向發展，電子式比流器替代傳統的電磁式比流器是趨勢，但是電子式比流器與傳統比流器的輸出形式有很大的不同，如何選擇和設計變電站層、過程層與間隔層保護測量二次設備之間的介面就成為要解決的關鍵問題。
本文按照國際電工委員會制定的電子式比流器標準IEC 61850-9-2，對電子式比流器數位輸出的實現方法進行了研究，主要內容包括過程層數位信號處理模組與編碼模組的整合、變電站層數據的紀錄與封包的分析。
過程層通訊模組是連接資料採樣裝置與間隔層保護監控設備的橋樑，本文採用MSP-430 F47187作為微處理器，將本文使用之無鐵芯式霍爾比流器所量測的數據進行接收，且合併處理，最後將完整的資料格式進行編碼後通過光纖網路傳輸到變電站層，並利用Wireshark軟體分析網路封包以及LabVIEW軟體記錄實驗結果。
在實驗量測過程中，輸入至電纜之感應電流為額定有效值600A，進行了額定電流100、120、20以及5％電流的量測、採樣波形的還原、自動化量測系統測試以及網路封包的分析，最後的實驗結果可知MSP-430與通訊模組之間的通訊並無異常，實驗所擷取之封包皆有符合IEC 61850-9-2規範格式。

Development of smart grid requires substitution of traditional electromagnetic current transformers by electronic current transformers. However, output formats of electronic current transformers and traditional electromagnetic transformers are very different. Therefore, the selection and design of the interfaces of the station level, the process level and the bay level become a key issue.
According to IEC 61850-9-2 standard, a digital communication interface for electronic current transformer is designed and implemented in this research. The main contents are the integration of processing and encoding signal modules in process level, as well as data records and packet analysis in station level.
MSP-430 F47187 is used as the central processor of the process and bay level interface module. It is the bridge from high-speed data sampling system in the process level to measurement and control device in bay level. It collects data from coreless Hall current transformers, then processes and encodes the data after packing total frame based on the standard. Finally, these data are transmitted to bay level using optical fiber. The packet format is analyzed by Wireshark and the results are recorded by LabVIEW.
In the course of the experiment, the induced current input of the cable is rated at rms 600A, measuring the range 100, 120, 20 and 5% of rms current, sample value waveform recovery, automatic measurement system test and packet format analysis. The final experimental results prove that there are no communication problems between MSP-430 and the module. All packets used in the experiment comform with the IEC 61850-9-2 specification format.
