In this paper, the theoretical and experimental characteristics of magnetic and electric fields in the vicinity of high voltage lines are investigated. To realize these measurements and calculations, we have developed some equations for two overhead power line configurations of 150 kV (single circuit, double circuit), based on Biotsavart law, image and Maxwell theories, in order to calculate the magnetic and electric fields. The measurements were done to a maximum distance from the tower of 50 m, at a height of 1m from the ground. These experiments take into consideration the real situations of the power lines and associated equipment. The experimental results obtained are near to that of the Biot-Savart theoretical results for a far distance from the tower; and for a distance close to the power line, the results from the image theory are in good agreement with the experimental results.

“…Electric and magnetic fields and workers' exposure to them at substations have been studied in many countries, for example in Greece [1], Belgium [2], Romania [3,4], Switzerland [5], Colombia [6,7], Cuba [6,8], Japan [6,8], Indonesia [6,9], Mexico [6,10], Thailand [6,11], and the U.S. [6,12]. For example, Tanaka et al [6] summarized the EMF measurement results of activities carried out inside and around 500-, 400-, 275-, 230-, 220-, 115-, and 110-kV power facilities in seven countries: Colombia [7], Cuba [8], Japan [8], Indonesia [9], Mexico [10], Thailand [11], and the U.S. [12].…”

Abstract-Earlier studies have shown that the occupational exposure of electric fields at 400 kV substations can be higher than the low action level of 10 kV/m set by the Directive 2013/35/EU. One possibility for decreasing the occupational exposure is to surround the worker with a Faraday cage. The objective of the study was to investigate how effective a Faraday cage is in decreasing the ELF electric field exposure during work tasks from a man hoist at a 400 kV substation. First, we measured the electric field exposure while performing maintenance tasks from a man hoist. We then constructed a Faraday cage around the man hoist and measured the exposure again, with hopes that the exposure would be sufficiently reduced to create a safe working environment. The Faraday cage was constructed from a steel net 0.5 m in width with 19-mm meshes. The net was made of hotdip galvanized steel wire, 1.0 mm in diameter. The net and the man hoist were then grounded. The maximum electric field without the cage was 28.8 kV/m, and with the cage, it was 0.5 kV/m. The electric field, therefore, was decreased by 96.8-99.9%, validating the efficacy of Faraday cages.

“…Furthermore, measurements of the magnetic fields derived from underground distribution systems in residential areas are described in [12] and [13]. Comparisons between the international specified limits for public and occupational exposure, and from EMFs and those measured inside outdoor substations are presented in [14]- [17]. In addition, theoretical calculations of EMFs based on computer programs are described in [16] and [17].…”

This paper presents the mean values of the resulting magnetic field in the low-frequency range, which were recorded during spring and summer near two-pole-type distribution substations in urban areas. The mitigation of the magnetic field that was achieved after covering the low-voltage (LV) fuse boxes with thin aluminum plates is also presented. The mean attenuation achieved is approximately 23% during spring and 18% during the summer at the region of up to 30 cm from the substations and at a height of 1.0 m from the ground, at the measuring points near the LV fuse boxes. All of the measured magnetic-field values that were observed were lower in comparison with those specified as limits and introduced by ICNIRP.
