As a reliable power network is crucial to deliver promised electric power, cable powerline monitoring in medium-voltage networks has a great importance for distribution system operators all over the world. A considerable rate of failures in cable powerlines is referred to the cable joints. Especially during the summer period, an excessive number of joints are subjected to explosion, causing outages in different points of the power network. To this purpose, in this paper, using a simple test setup presented in a previous work, the effects of temperature on the cable joint tan delta measurement have been evaluated. In fact, the temperature is one of the possible causes of faults and, from the patterns presented in the results, the hypothesis seems to be confirmed.

Abstract

As a reliable power network is crucial to deliver promised electric power, cable powerline monitoring in medium-voltage networks has a great importance for distribution system operators all over the world. A considerable rate of failures in cable powerlines is referred to the cable joints. Especially during the summer period, an excessive number of joints are subjected to explosion, causing outages in different points of the power network. To this purpose, in this paper, using a simple test setup presented in a previous work, the effects of temperature on the cable joint tan delta measurement have been evaluated. In fact, the temperature is one of the possible causes of faults and, from the patterns presented in the results, the hypothesis seems to be confirmed.
