Normalization of double-circuit overhead line magnetic field inside Khrushchev building

This paper deals with the mitigation of 110 kV double-circuit overhead line magnetic field inside five-story Khrushchev buildings. We show that the magnetic field can exceed the reference level 0.5 μT in 90 % part of living space. To mitigate the magnetic field, we propose the inverted L-shaped grid...
