Event Reports and SER
Standard 15-, 30-, or 60-Cycle Event Reports
Event DIF (Differential Event Report)
The differential event report contains the operate and restraint currents in a
given differential element along with the second- and fifth-harmonic content
of the current. The status of the restrained and unrestrained differential
elements, the fifth-harmonic alarm, the REF function, the Relay Word bits
