Abstract
The results of field tests have shown, that the behaviour of the restriking earthfault in a cable is complete different in isolated and compensated networks. This paper will present these differences in detail and point out the influence to the corresponding earthfault detection methods and the corresponding neutral point treatment. Due to the different behaviour, there are new possibilities to reduce the current via the fault location. One of these new concepts will also be presented in this paper.
