TR-100+ Digital Fault Recorder


OBSOLETE, please see replacements TR-3000 & DR-300. AMETEK Power Instruments will still offer support for the TR-100+.

The AMETEK TR-100+ is a fully featured Digital Fault Recorder with the capability to capture and analyze short transient events, longer-term disturbances and trend input quantities such as RMS, frequency, harmonics, power and power factor. The TR-100+ meets regulatory compliances including PRC-002-2.


  • Transient fault recorder - post fault analysis to verify protection and circuit breaker operations, fault clearance times and distance to fault
  • Disturbance recorder - extended recording and logging for slow disturbances and steady state RMS values, harmonics and optional real power and power factor
  • Power quality monitor - voltage and frequency profiles, voltage dips and surges, loss of supply, and harmonic content
  • Fault locator - calculates distance to fault based on configurable line model
  • Real time monitor - view analog, digital inputs and computed values in near real time
  • On-line switchgear monitor - Used to identify condition based service time for switchgear by accumulating contact wear
