SATEC BFM-DFR – Multi-Circuit Digital Fault Recorder

The SATEC BFM-DFR is a modular, DIN-rail mounted digital fault recorder engineered for substation digitalization in retrofit projects. It monitors up to 12 three-phase current channels with shared or dual independent voltage sources, capturing fault events with precision at up to 40× nominal current.

The BFM-DFR's modular design allows installers to tailor the device to each application's exact channel count, I/O requirements, and communication interface needs – without over-specifying hardware.

Digital Fault Recording

  • Up to 40 simultaneous waveform channels
  • Fault recording at 40× nominal current – captures even severe transient events
  • Pre-fault and post-fault recording windows (configurable)
  • High sampling rate for accurate fault analysis

Multi-Circuit Monitoring

  • Up to 12 three-phase current channels per device
  • Supports shared voltage or two independent 3-phase voltage sources
  • SATEC HACS (High Accuracy Current Sensor) compatible inputs

Communication & I/O

  • IEC 61850 for digital substation integration
  • Extensive I/O options for protection and control signals
  • Configurable communication interfaces per application

Modular Design

  • Mix and match current channel modules, I/O modules, and comm interfaces
  • Fits new build and retrofit substation projects
  • DIN-rail mounting
