Description	Příspěvek se zabývá možnostmi lokalizace zemních spojení v elektrických sítích vn. Jsou zde prezentovány dvě metody, jedna pro lokalizaci v zkruhované síti a druhá pro lokalizaci v síti paprskové (cs) A single phase-to-ground connection is a fault that appears very frequently in MV lines of distribution networks. This fault can result in injuries of persons that occur near to the point of the fault and it can result as well in an interruption in the supply of electricity. Most distribution networks are operated as a compensated network, where an immediate discon-nection of the fault is not necessary. The line can be operated without interruption, but only under condition that the fault is quickly loccated and eliminated. It means that a prompt fault identification and appropriate location guarantee at least uninterrupted energy supply. At present, digital protections using the admittance principle are able to identify quite reliably a single phase-to-ground connection and to determine the affected feeder. Still, the location of the fault presents a task yet to be solved. The main problem of a fault location consists is a low value of the fault current during a single phase-to-ground fault in compe A single phase-to-ground connection is a fault that appears very frequently in MV lines of distribution networks.
