Title: Design and testing for a system to monitor temperature in underground electric power transmission cables. [CMARS]

Abstract

The development and evaluation of a computer based system to calculate temperature and ratings of HPOF pipe-type cables in real-time are described. Algorithms applying modern estimation and identification technology to perform these tasks were designed and demonstrated on two operational cables. Test results give estimates of conductor temperature within +- 7% of the actual conductor temperature over a 0/sup 0/C to 125/sup 0/C range. Although the scope of the present research was limited to HPOF pipe-type cables, the concept and major components of the system could readily be applied to gas-insulated cables, duct bank installations, and direct buried cables. The approach also lends itself to implementation on either a central dispatch computer or distrributed local micro-processor units.
