FIELD: electrical engineering. SUBSTANCE: distinguished feature of proposed process consists in formation of magnetic field of invariable polarity by electrostatic machine in cable. This field is traced along route and disappearance of magnetic field above point of fault is registered by device measuring magnetic values, for instance, by ferroprobe tesla meter. EFFECT: increased accuracy, reduced consumption of materials, diminished time of search for location of fault, simplified process of search. 2 dwg
