Abstract

In this paper, we investigated the extremely low frequency (ELF) magnetic field environment in a 77 kV/6.6 kV substation. In order to clarify the influences of the line current conditions onto the ELF magnetic field environment, we carried out the simultaneous measurement of the line current and magnetic field distribution in the substation on-site. From the measurement data, we could quantify the actual line current conditions in the substation. Based on the current conditions, we could characterize the magnetic field environment. In addition, measurement of an elliptically polarized locus of magnetic field using the amorphous wire 3-axis magnetic field sensor is discussed
