scope:
Gives 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. No account has been taken of possible effects of moisture migration on the thermal resistivity of the soil.
