The relationship between the electric and magnetic fields along with soil resistivity is very important for direct lightning stroke. In this paper, the electric and magnetic fields produced by a parallel quadruple high voltage power lines (PQHVPL) have been measured. The measured fields are substantially high compared to the fields coming from conventional 132 kV and 275 kV power lines. The correlation between electric and magnetic fields emitted from PQHVPL and soil resistivity in the ground below the lines has also been investigated. The electric and magnetic field digital exposure system (EMDEX) hardware and software are used to measure and analyze the results. It is found that the electric field is higher at high soil resistivity and is lower at low soil resistivity.
