“…Specifically in [10], measurements of magnetic-field profiles around a specific substation have verified that adding a substation under an existing transmission line does not increase the magnetic field beyond the substation boundary. In [11], magnetic fields in a 187/66-kV substation are calculated for various current conditions and described in terms of contour plots. In [12], the magnetic fields generated by a distribution substation were measured and calculated, based on a computer model that takes into account currents in the grounding systems, distribution feeder neutrals, overhead ground wires, and induced currents in equipment structures and ground grid loops.…”

“…Since then, numerous studies had been made, some supporting the results of this study while others did not. In parallel to this, there were also engineering studies that investigate magnetic field from transmission lines and substations and explore ways to minimize these [2][3][4]. This paper reports on a study carried out to characterize magnetic field from several distribution substations in and around Putrajaya, a new administrative center of Malaysia.…”

Magnetic field spot measurements were done at four distribution substations, three of them were of exactly the same design and capacity, while the fourth has similar design and half the capacity. The data collected were compared with one another. Taking into account loading of the substation during measurement period, it was found that magnetic field distributions were similar, with high peaks at low voltage cable connections to transformers and low-voltage switchgears. Magnetic fields decayed rapidly with distance. Magnetic field longitudinal and transverse linear plots crossing the middle of the substations were also constructed and these were also found to be similar. Magnetic field parameter plots give information of magnetic field of which the general public may likely be exposed to. These were found to be lower than the limit recommended by the most standards.
