JSIS Meeting
October 2017

2. Test Methodology Set trigger limits – frequency, voltage, etc.
Create waveforms with test set
State sim for step tests
DFR records from field units for actual events
COMTRADE playback
Play waveforms into DFR/DDR
Verify timestamp of event, accuracy of waveform, and any computed values
Compare measurement with input signal
Test back-to-back events

18. DFR Evaluation Criteria
Length and reporting rate of event records
Reporting rate of continuous recording
Calculated/sampled values vs. point-on-wave
Computed values – power, frequency, phasors
Data formats – .csv, COMTRADE, etc.
Expandable storage? Moving components?
Time synchronization – GPS? IRIG-B?
Architecture: external CTs/shunts, modules, etc.
Portability and ease of installation
Access to records
