Investigation of Electromagnetic Radiation from CRUTECH Electric Power Substation
Subject area: Science,Engineering and Technology · Area of research: EM FIELD
Abstract
The aim of this study is to empirically quantify the electric field intensity and the associated magnetic field strength emitted from an injection sub-station and compare results with the generally accepted safety standards such as the International Committee for Non-Ionization Radio Protection (ICNIRP) Standards. For the purpose of this study, We adopted the method of obtaining measurements using appropriate Instrumentation and Employing computational capabilities in order to simulate the propagation environment for easy analysis. MUSTOOL (MT525) Electromagnetic radiation meter a portable field survey instrument that conforms to international standards was used. The switch yard was modelled as a rectangular box, while measurements were taken at specific locations around the box. These locations were sixty in number each having their corresponding x and y axes. At each point, measurements were obtained at three different heights of 1m, 1.5m and 1.75m at each point. But preliminary measurements showed that the Electric field was constant at all these heights. The magnetic field strength measured at a height of 1.5m, 1m, and 1.75m, had a maximum value of 54?T, 57.699?T, and 29.93?T, respectively. The Electric field intensity measured at a height of 1.5m peaked at 0.293kV/m. Contour plots show areas of interest in this investigation. It was noticed that the contour lines increases inwards. This indicates a buildup of magnetic field or electric field at these areas of interest. This was further buttressed by the surface plots, which highlights these areas of interest as elevations on the surface. When compared to the generally acceptable safety standard for public and occupational exposure to power-frequency EMFs. These values were less and within the limit recommended by International Commission on Non-Ionizing Radiation Protection (ICNIRP).
