Abstract :
The same basic principles on which the methods of power cable protection against overloads are based are summed up by different criteria and formulations within ANSI/IEEE and CENELEC/TEC publications. The studies carried out by the technical committees of these organizations have been examined and compared, in order to point out not only their differences, but also their complementary aspects. By combining the two approaches, it has been possible to outline a “third way” to determine the admissible duration of overload currents and define intermediate criteria for the emergency ratings of cables and for the coordination of protective devices
