Calculation of the cyclic and emergency current rating of cables - Cyclic rating factor for cables of all voltages, with partial drying of the soil1 Scope This part of IEC 60853 gives a method for calculating the cyclic rating factor, for cables of all voltages, where partial drying out of the surrounding soil is anticipated. The method is based on one of the three methods published in a CIGRE1 document. The method is applicable to any type of cable, but it is recommended that it should be applied only to installations of one multi core cable or to three single core cables or to groups of
