Calculation of the cyclic and emergency current rating of cables. Part 1: Cyclic rating factor for cables up to and including 18/30(36) kV

PUBLISH DATE 1985

Calculation of the cyclic and emergency current rating of cables.

Part 1: Cyclic rating factor for cables up to and including 18/30(36) kV.

Methods for calculating the **cyclic rating factor** for cables where the *internal thermal capacitance* can be neglected include the following:

  • Using steady-state thermal models that assume instantaneous equilibrium with the ambient temperature.
  • Applying simplified thermal calculations based on the cable's thermal resistance and the external environment conditions.
  • Employing empirical or standard-based correction factors provided in cable rating guides or standards.
  • Calculating the cyclic rating factor by relating the maximum allowable conductor temperature to the average ambient temperature over the cyclic period.
