Development of smart grid makes new requests to fault recorder, for this reason, referring to DL/T 663-1999 standard the performance characteristics of digital fault recorder （DFR） based on IEC 61850 standard are summarized. According to requirements for the appraisal of digital fault recorder during system-level testing of digital substation, the testing methods for digital fault recorder are researched. In allusion to the performance test of DFR, a testing system is constructed, and combining with related standards and testing experiences the test contents to be performed in overall testing of DFR are listed. In the listed contents, technical requirements of such testing items closely related to the performance characteristics of IEC 61850 as the inspection of the standard ability of GOOSE messages, the test of abnormal bit identification of the quality of sampled data, the test of abnormal bit identification of synchronization of sampled data, the inspection of synchronization of sampled value, the inspection of decoding of sampled value, the inspection of resolution of GOOSE events, the testing of time alignment and time-keeping accuracy, alarming of real-time monitoring of message and record inspection and inspection of switch signal alteration are emphatically analyzed. Typical problems existing in the testing process of DFR are discussed and corresponding solutions are given.
