Abstract
This paper presents first results from a pilot project on
using fault indicators and self-healing in medium voltage distribution grids. Directional
earth-fault indicators were chosen and deployed in real environments to test their functionalities
and quantify their benefits for efficient grid operations. Self-healing concepts using these
indicators will be tested in the described project. Different communication schemes will be
explored in order to find the most cost-effective solutions. Theoretical potentials of the expected
benefits of the fault indicators located at different positions in the grid were modelled and will
be compared to the results from field tests.
