Introduction
Replace the words “This standard” in the first paragraph by “This part of IEC 60853”.
Replace the second paragraph by the following two new paragraphs:
Part 2 of the IEC 60853 series provides manual methods for calculating cyclic rating factors
for cables whose internal thermal capacitance cannot be neglected; in general this applies to
cables for voltages greater than 18/30 (36) kV. It also gives a method for calculating the
emergency rating for cables of any voltage as well as providing a means of calculating the
temperature response of a cable to a current that changes in discrete multiple steps.
Part 3 of the IEC 60853 series deals with cyclic rating factors for cables of all voltages when
partial drying of the soil occurs.
1 Scope
Delete, in the first paragraph, the last sentence beginning “Methods for dealing ……”.
