Abstract :
The Neher-McGrath (NM) method for calculating temperature rises and current-carrying capacities of insulated nonshielded power cables rated 0-2000 V phase-to-phase is described. The concept of the thermal circuit is explained, NM equations for calculating thermal resistances are given and sample calculations are presented.
