Abstract

Supplying electric power to central metropolitan areas is challenged by free area to build overhead high voltage transmission lines (OHTL). A solution is to share existing right-of-way (ROW). As a result, there are two or three voltage levels OHTL and oil and gas underground pipes. This paper presents a method to calculate magnetic field human exposure in the proximity of an utilities corridor with 345 kV, 230 kV and 88 kV OHTL in Sao Paulo metropolitan region, considering power flow direction and phase shift between concerned OHTL.
