The invention relates to an equipment for determining fault locations and fault resistance on a live network. The invention is characterized in that the input (21) of the measuring and controller unit (2), on the one hand, connects to the secondary windings of the substation's (1) current transformers (1a), and on the other hand, to the output of the zero sequence voltage-signal conditioner (1b), its data output (22) connects to the data input (31) of the data processing unit (3), the controller's output (23) connects to the controller input (41) of the injecting unit (4) while the injecting unit's (4) output (42) connects to the star point via the coupling/filtering unit (5). The invention relates also to the procedure for determining ground fault locations and fault resistance. |
