Transient Fault Records in Substation we are using a DDFR
(Distributed Digital Fault Recording) System:-

Transient Fault Records (also known as Oscillography
records) that are recorded in protection relays will be
retrieve by the DDFR and stored in its internal memory
space. All Transient Fault Records will be archived using a
naming convention that will make it easy for users to
relate the Transient Fault records with a particular
substation fault. Each record will be stored with a name
that includes the exact date and time that the record was
initially triggered. If the Transient Fault record was
originally recorded in the relay as a COMTRADE file, the
DDFR will store this record in its native format; if the
protection relay stores it’s record in another format, such
as a CSV file, the DDFR will automatically convert this
file into the COMTRADE-1999 format so that the record can
be analyzed using a standard COMTRADE viewer.
