Abstract The paper emphasizes the results of the first systematic electromagnetic field measurements performed in high and very high voltage substations belonging to the Romanian National Power Grid in order to face the requirements of the EU Directives regarding the human exposure to the electromagnetic fields. In the first part of the paper, the experimental field measurement results from a recently rehabilitated 400/220 kV substation belonging to the Romanian Transport and System Operator (TSO) Company are presented. It follows the experimental field measurement results from two 110/20/10 kV electricity distribution substations. The high intensity field zones are highlighted and the highest field value found is compared with the exposure limits given by the actual legislation. In the second part of the paper, analytical field computation methods are approached following two main reasons: to validate the experimental results and to proof the analytical methods efficiency in evaluation of the electromagnetic field values in the neighborhood of the power devices from complex systems such as the substations. The final conclusions of the study performed and the actions proposed to be taken in practice finish the paper. Copyright © 2010 Institute of Electrical Engineers of Japan.
