DBF
  • Main Characteristics
  • Box of 19 rack and 3U high.
  • Common hardware platform with DDS, SMOR and other
    GE Multilin products
  • It can be integrated in the DDS and SI
  • Compatible with the software GE-NESISTM

3
Characteristics
  • Digital technology, multiprocessor based.
  • Integration of
  • Protection.
  • Monitoring and Analysis.
  • Oscillography of 16 samples per cycle.

4
Main Functions
  • Breaker failure with two independent tresholds.
  • Internal arcing protection.
  • Current metering.
  • Breaker Health Monitor (kI2t ).
  • Event Recorder, last 165 events.
  • Oscillography, 4 records of 62 cycles.

5
Protective Functions
  • Breaker Failure
  • Three-phase Ground overcurrent units.
  • BFI single-phase three-phase with independent
    timers and levels to start and adapt the breaker
    failure.
  • Operation failure detection. Applicable where
    there is a mechanical fault (direct trip without
    current presence).

6
Protective Functions
  • Internal arcing protection
  • Three-phase very sensitive overcurrent units
    timer to detect electrical arcing between the
    contacts of the breaker when it is opened.

Metering Monitoring
  • Current metering (Ia, Ib, Ic, In).
  • Breaker health monitoring.
  • Event recorder, last 165 events.
  • Oscillography, 4 records of 62 cycles.
  • Configurable inputs/outputs.

9
Local Communication
  • Integrated MMI Display
  • 2 line display and 16 alphanumeric characters.
  • 20 keypad display with three password levels.
  • Current value monitoring (RMS)
  • 16 configurable LEDs for signalling.

IA IB IC IN 100.0 100.0 103.1 1.5
10
Remote Communication
  • 3 RS232 Communication ports (DB9).
  • 1 on the front (RS232).
  • 2 on the back (1) RS232 (1) RS232/PLASTIC
    O.F./GLASS O.F.
  • 300 to 19,200 Bauds.
  • Software GE-INTRO
  • Current values, fault report, relay setting,
    osccillography data collection.
  • Three password level.
  • IRIG-B for synchronization.

Flexible Mounting
  • Semi-flush mounting. Rack 19 3 U high.
  • Front Display, keypad and LEDs for signalling.
  • Power Supply 48 VDC and 110/250 VDC.

12
High quality and reliability
  • Design
  • Modular and flexible plattform.
  • CE marking.
  • Wide operation temperature range
    -20 ºC to 65 ºC.
  • ANSI and IEC standards.
