POWER TRANSMISSION CABLE LINE DAMAGE LOCATION METHOD

摘要

FIELD: electric power net engineering. SUBSTANCE: method includes current spreading picture scaling by cable line feeding by direct current from unipolar source and magnetic field generated by this current following along cable trace by ferrozond teslameter using. Magnetic field polarity inversion or magnetic field disappearance, either drop down indicates damage location point. EFFECT: higher accuracy of damage location determining, shorter operation time.
