Zusammenfassung:	FIELD: electrical engineering, in particular, systems for digital information transmission. SUBSTANCE: method involves additional measurement of test current in broken piece of remote power supply circuit in same direction as remote power supply current. Index of non-attended intermediate node before broken piece of remote power supply circuit is calculated using equation , where Iopp is test current in broken piece of remote power supply circuit in opposite direction with respect to remote power supply current, Idir is test current in broken piece of remote power supply circuit in same direction as remote power supply current, Ina is current of non-attended intermediate node, when test source has opposite voltage polarity with respect to polarity of remote power supply voltage. EFFECT: increased precision of finding, simplified operations.
