Název v původním jazyce

Temperature rise of a cable of type "NHKY" loaded by nominal and short-circuit current

Popis výsledku v původním jazyce

The paper deals with the temperature rise of a one-phase cable of type NHKY in the nominal and short-circuit operations. The former case is aimed at calculation of the steady-state temperature field for a long-term load of the cable by the nominal current. The latter one determines the time of loading the cable by the short-circuit current for which the maximum temperature does not exceed the admissible value. The task formulated as a weakly coupled problem is then solved by the FEM-based professional program QuickField and a user program NESTAC. The theoretical analysis is supplemented by an illustrative example, discussion of its results and sugges-tion of possibilities of further improvements of the pre-sented algorithm.
