The SHDFR_B power fault recording device is a new-type IEC 61850-compatible imbedded recorder developed by Shuanghe. The device integrates such functions as transient state recording, steady state recording, real-time operational monitoring, fault location and analysis. Modeled on the IEC 61850 standard, it implements the traditional functions of the recorder and at the same time, communicates with the recording manager and remote dispatch through the MMS communication method specified by the IEC 61850-8-1.
