METHOD OF SEARCHING FOR CABLE CORES OR WIRES FEEDING CONSUMERS Russian patent published in 2020 - IPC G01R19/04 

FIELD: electrical equipment.

SUBSTANCE: invention relates to electrical engineering, in particular to determination of source and wires, from which consumers are fed in branched electrical networks without disconnection of loads. At one end of cable or wire bundle at consumer connection point to one phase of cable or to one wire from wire bundle multivibrator output is connected, periodically connecting at preset time intervals cable conductor or wire with zero wire or grounding through resistance, and at power supply source on other end of cable is determined by oscillation of the arrow of current-measuring mites, covering at first cable or bundle of wires, and then wire, to which output of multivibrator with resistance is connected.

EFFECT: technical result consists in the development of a method, in which the consumer has current pulses imparting current pulses generated by periodic connection to the wire of the additional resistance line and catching current pulses at power supply by current-measuring pliers as per pointer oscillations.
