Distributed Temperature Sensing (DTS)
- Southwire #
- HVUD35
Distributed Temperature Sensing (DTS) systems use fiber-optic technology to provide continuous, real-time temperature monitoring along the entire length of high-voltage cable networks. By measuring temperature at every point of the cable, DTS provides complete thermal visibility, enabling early detection of hot spots, improved asset management, dynamic cable rating, and enhanced system reliability without requiring distributed power sources or conventional point sensors.
