The authors report the results of a recently completed major project on power cable transient calculations. It used a fundamental analytical method using a lumped parameter model for computation of transient ratings of buried power cables. An account is given for past work in the field of thermal transients in buried cables. A full description of the mathematical model is given. A summary of the state-of-the-art is provided. Developments relevant to the analysis of groups of unequally loaded and/or dissimilar cables and cables located in ductbanks or thermal backfills are presented. >
