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 clue 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.
