Junction Box Slow Control System

• MAIN JOB JB
  OUTPUT CONTROL
• (BREAKER OPERATION CURRENT
  MONITORING)
• System uses 8 of the 48 fibres in the undersea
  cable
• Based on three control cards built in two
  different technologies.
• Technology (1)
• 2 identical cards (A,B) powered from different
  technology (linear, switching) power supplies
• and
  different 240V secondaries
• Communicate through 160Mb/s G-links _at_ 1550nm,
• Agilent HDMP-1022/1024 transmitter/ receiver
  chip set
• Photon Techno PT5543-13-3-SC laser
  emitter PT6143-155-SC receiver
• Associated firmware
  embedded in ALTERA 7256S FPGAs.
• Each card can stream 16-bit digitized data from
  48 internal junction box temperature and humidity
  sensors,
• breaker status
• 24bit data at 2.6kHz sampling from a group of 4
  MACC plus inductive current sensors (Mfr
  Hitec, NL).
