RE: DFR or TFR
Power Fault Recorder may be provided with TFR or/and DFR. See:
http:
Disturbance recorder/logger—analyses power system stability by recording reclose sequences, power swing, and frequency oscillations.
Transient fault recorder—post fault analysis to verify protection and circuit breaker operations, fault clearance times. See:

RE: DFR or TFR
All our recent installations have been DFRs rather than TFRs.
