Power Circuit Monitoring in the Czech Republic

In 2009 Brugg Cables installed a new 110 KV power circuit within the city limits of Prague. To protect valuable assets and to gain experience applying Distributed Temperature Sensing (DTS) technology the end customer chose to equip the new circuit with a fiber optical sensor cable and permanently monitor the temperature profile with an AP Sensing Linear Heat Series instrument.

Approximately half of the power circuit is deployed in a utility tunnel and the other half is buried in tubes / trenches. Using AP Sensing’s flexible DTS design, they defined 49 monitoring zones in-line with the varying installation conditions along the circuit.
