  • METHOD AND DEVICE FOR LIMITING SECONDARY ARC CURRENT OF EXTRA-HIGH VOLTAGE/ULTRA-HIGH VOLTAGE DOUBLE CIRCUIT LINES ON THE SAME TOWER
    Publication number: 20120212862
    Abstract: A method and a device for limiting secondary arc current of an extra-high voltage/ultra-high voltage double circuit line on the same tower. The method comprises the following steps: determining the type of a single-phase-to-ground fault when the extra-high voltage/ultra-high voltage double circuit line on the same tower has a single-phase-to-ground fault (S501); selecting a reactance value of a neutral grounding reactor according to the type of the single-phase-to-ground fault (S502); and switching the extra-high voltage/ultra-high voltage double circuit line on the same tower to the selected reactance value of the neutral grounding reactor (S503). Thus the reactance value of the neutral grounding reactor is not constant, but is changed along with the operating conditions of the power transmission line, that is, the reactance value of the neutral grounding reactor is controllable.
