dfrThe TRANSCAN DFR is a multifunction data collection platform for data collection and local storage of triggered and continuous recordings and phasor data. It uses an expandable chassis capable of monitoring up to 64 analog and 128 digital inputs. Cross-trigger and remote trigger capabilities are supported which enable integrating multiple DFR subsystems in a very large DFR installation.

Data Collection:

  • Up to 64 analog, 128 digital inputs
  • Synchronized Phasor Measurement

Triggers and trigger-initiated recordings:

  • Various fault, and power and frequency triggers
  • Fault recording at user selectable rates – typically at 96 samples per cycle
  • Analog values for NERC DDR and synchrophasor applications
  • Cross-trigger and remote trigger capabilities

Phasor Data Streaming:

  • 30 or 60 frames per second, IEEE C37.118 compliant
  • Up to 60 phasor values per frame, individual phases and Positive Sequence phasors
