Underground Power Monitoring in Latvia

In 2017, an AP Sensing fiber-optic DTS (Distributed Temperature Sensing) solution was selected to monitor power cables on two underground circuits.

The Latvia power utility selected a DTS solution with SmartVision and RTTR (real time thermal rating) when building a new substations in Skaste Riga. The power cables form two independent 110kV underground circuits within Riga, running 4km and 3km each. The installation involved one DTS N4425A device with six channels.
