IEC 60287-1-2:1993 Electric cables; calculation of the current rating; part 1: current rating equations (100% load factor) and calculation of losses; section 2: sheath eddy current loss factors for two circuits in flat formation
Provides a method for calculating the eddy current losses in the metallic sheaths of single-core cables arranged as a three-phase double circuit in flat formation. The method described provides the coefficients H (correction for sheath resistance), N (in
