Calculation of the cyclic and emergency current rating of cables - Cyclic rating factor for cables of all voltages, with partial drying of the soilWhat is BS IEC 60853 3 Cycling and emergency current rating of cables about? BS IEC 60853 3 is part of IEC 60853 on calculation of cyclic and emergency current rating of cables. BS IEC 60853 3 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 outlined in BS IEC 60853 3 is based on one of the three methods published in a CIGRE1 document. The
