MAGNETIC FIELD NORMALIZATION IN RESIDENTIAL BUILDING LOCATED NEAR OVERHEAD LINE BY GRID SHIELD
Keywords:magnetic field, shielding, overhead line, right-of-way, reference level
AbstractThis paper deals with the magnetic field mitigation of 110 kV trefoil single-circuit and double-circuit overhead lines by grid shields. The shields under study are made of aluminum conductors connected in parallel. These shields are mounted on the walls of the building. We study the efficiencies of plane and U-shaped grid shields as the dependence from the quantity of metal. As the result, we show that the plane grid shield does not supply the required efficiency of magnetic field mitigation in corner areas of the building. At the same time, the U-shaped grid shield having equivalent quantity of metal allows to mitigate the magnetic field to the reference level 0.5 µT in more than 97 % part of the building.
