    Abstract
    Fault current indicators for detecting grid faults are important elements in smart distribution grids. The indicators can be used for smarter handling of faults and enable faster restoration of electricity supply, giving potentials for reducing both frequency and duration of interruptions in the electricity supply. A novel methodology for reliability of supply analysis has been developed, focusing on the effect of combinations of fault current indicators and remotely controlled disconnectors as well as self-healing functionality. Fault indicators and self-healing solutions are being tested at several locations in the distribution grid. This paper describes the new methodology and presents promising results from case studies on real MV distribution grids. Experiences from establishing the demo infrastructures are also described.
