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.

? Supporting IEC 61850.
? With a high-reliability industrial-level all-imbedded structure, the device runs the imbedded Linux OS; anti-virus, it provides reliable network protection.
? The device allows for free combinations of the transient and steady state recording methods, while steady state data can be saved for more than seven days.
? Two independent hardware systems are adopted for the transient state recording unit and the steady state recording unit so that a recording unit, if damaged, will not affect the normal operation of another.
? Powerful waveform analysis & processing function.
? Supporting the two-terminal fault location function.
? Supporting multiple clock synchronization methods such as pulse per second, minute per second, IRIG-B, and NTP.
? Its hardware and software both have a modular design; an inter-card alarm monitoring mechanism is adopted to facilitate servicing and maintenance.
