要約(日本語): High temperatures are generated in power conductors during faults becauseof the high currents that are involved. Because fault duration is normally short,the loss in tensile strength during heating is neglected, notwithstanding the higher temperatures that are genereated.Contrary, however, the loss in tensile strength during the cooling process isquite significant and should always be taken into account. This is because theloss in tensile strength is cumulative and secondly, because faults cannot beavoided in power systems.The degradation of a conductor is directly related to the maximum tempeartureas higher temperatures lead to longer cooling time.
