FIELD: electrical engineering. SUBSTANCE: device used in locating defects on cable line to ensure desired contact resistance at defective point is characterized in stepless operation and in that low-voltage DC supply with low internal resistance and high-voltage supply with high internal resistance are connected to defective cable conductor in parallel opposition through current cut-off diode isolator and adjusting device such as variable series resistor. EFFECT: improved efficiency, reduced mass and size of device. 5 dwg
