This paper is concerned with methods of ithg the build-up of transient voltages between sheath and armour in long armoured power cables. Calculations by a frequency dependent cable model demonstrate that this voltage can be efficiently h i t i t e d to an acceptable level by introducing sheath-armour bondings at regular intervals, or by using a semiconductive sheath-armour interlayer. The paper investigates the required minimum length between bondhgs, as well as the required conductivity of the sheatharmour i…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
