The advantages of a dedicated, standalone DFR are well known: natively synchronised fault records, large record storage capabilities, high sampling rates, numerous types of triggers, and large numbers of analogue and digital recording channels. The main disadvantage to the dedicated DFR is cost: a dedicated DFR must be directly wired to every current, voltage, and status point, resulting in an installed project cost easily ten times the material cost of the DFR itself. However, IEC 61850 process bus makes dedicated DFRs affordable again, by eliminating all field wiring necessary for installing a DFR.
