Calculation and Measurement Analysis of Transformer Station Low-Frequency Electromagnetic Fields in the Framework of Legislation on Protection from Non-ionizing Radiation

Modern researches of electromagnetic fields (EMF) are based on the concept that complicated theoretical investigations are resulting in appropriate design solutions, and they are almost exclusively developed as applied researches. Generally, two directions are presented. The first one is based on the simplification of numerical calculation models, and the second one is based on models of objectified physical measurements in hard conditions. In both cases, however, the result is the same objective, which can be summarized as follows: create the optimal variant of solving the impact of the EMF, both in existing and new power facilities. The paper presents the analysis of numerical calculation of the EMF of distribution substation and detailed operational measurement program, which includes all measurements in stationary state with measurement location. The analysis of calculations and measurements results must indicates the possible dangerous places and gives the recommendations of measures for elimination of electromagnetic influences or their reduction to an acceptable level, according to the Regulations.
