Abstract
A method and an arrangement are disclosed for determining the direction of excess currents in energy supply networks, such as in medium voltage networks. An exemplary method and arrangement render it possible to reliably isolate a point of fault caused by a short-circuit or excess current, even if switching systems of the energy supply network do not include a capacitive pickup. Exemplary arrangements include an energy supply network which connects, via a transformer, a medium voltage network to a low voltage network.
