Abstract :
This paper describes the development and evaluation of a system to calculate temperatures and ratings of HPOF pipe-type cables in real-time. Algorithms applying modern estimation and identification technology to perform these tasks have been designed and demonstrated on two operational cables. Test results give estimates of conductor temperature within ±7% of the actual conductor temperature over a 0°C-125 °C range.
