Gives methods for calculating the cyclic rating factor for cableswhere the internal thermal capacitance can be neglected.The simplified methods in this standard require only a knowledge ofthe full shape of the load variation for not more than 6himmediately preceding the time of maximum temperature and anaverage value for times before that.
