    Sammanfattning : Today cables replace overhead lines in distribution systems and cause higher system capacitance and higher capacative fault currents. This fault current, in the fault location, is limited by a Petersén coil and a resistance in parallel when a fault occurs in so called “high impedance grounded systems” which are commonly used in Europe.
