This webinar will present the 2019 PES Prize Paper entitled “Rating of Underground Power Cables with Boundary Temperature Restrictions”. This paper is selected as one of two PES prize papers among about 2000 papers published in all PES transactions over the past 3 years. The subject of the paper is about a new cable rating method for actual industry applications. The usual way of rating the electric power cables is to compute the current such that the conductor temperature does not exceed the specified limit. The procedures for ampacity calculations are well established and are part of several international and national standards. However, in several countries, another restriction is imposed on the maximum current the cable can carry. This restriction limits the temperature rise at a point other than the cable conductor. In North America, a notion of the “boundary” temperature limit is sometimes entertained. The boundary can refer to the cable surface but also to the edge of the duct bank or a backfill. The paper proposes new solutions to such problem including calculation of the dynamic ratings. It not only introduces a computational procedure to calculate ampacities based on boundary temperature restrictions but also illustrates how the new algorithm can be applied in practice for several cable design situations.
