ABSTRACT

This paper presents an optimization algorithm applied to the rating calculation of unequally loaded electric power cables.  Whereas standards spell out the principles of rating calculations for single and identical equally loaded cables, the common situation where the cables in a trench are of different construction is given only a

scant treatment.  The paper does not introduce any new calculation method but addresses an issue of what is the best method of loading groups of cables in a common trench.  To answer this question, an optimization algorithm utilizing barrier method is introduced and its application illustrated for a complex practical cable arrangement.
