Abstract

(ENG)The overvoltages between screens of the sectionalized joints depend not only on the chosen surge voltage limiters, but also on the type of bonding lead cable used to connect them. Connection cables of unipolar type instead of coaxial lead to higher overvoltages. This negative influence is accentuated the longer the length of the bonding lead cable. This article demonstrates the use of unipolar cable is equivalent to increasing the length of the cable more than 5 times that of the coaxial cable. The article also analyses the voltage distribution between each screen of a joint with respect to earth.(SPA)Se presenta las sobretensiones que aparecen en las pantallas seccionadas de los empalmes de los cables de alta tensión cuando una sobretensión transitoria recorre el cable. Los casos estudiados corresponden a configuraciones cross-bonding con y sin limitadores de sobretensión.
