Temperature Monitoring of Power Cable Junctions in an Underground Cable Trench

Application

Temperature monitoring of power cable junctions in an underground cable trench

  • Narrow underground cable trench with high voltage cables (HT (6.6 KVA) and LT (400 V))
  • High temperature at the junction due to high voltage power.
  • Currently no temperature measurement system in place.

Challenges

  • Threat of fires due to high temperature cable junctions.
  • Customer wants to add temperature measurement points for plant safety.
  • High voltage cables generate high levels of electric noise.

Solutions

  • Wireless temperature measurement
    gateway x1, transmitter (YTA) x1
    repeater x1: between gateway and YTA.
  • High quality wireless communication was confirmed.
    With repeater at center: The packet error rate was 0%.

Benefits

  • Eliminates wiring costs.
  • Robust communication where other wireless solutions failed.
