Real Time Thermal Rating Systems and Distributed Temperature Sensing Technologies – Benefits and Uses within the Transmission and Power Sector

Real Time Thermal Rating (RTTR) systems and distributed temperature sensing (DTS) technologies have been used within power cable condition monitoring to rate cables since the 1990’s.  A well documented power cable failure in Auckland 1998 shut down the city’s central business district. As a result, this recognised the benefits of incorporating DTS and RTTR into power transmission operations.
