Computation and measurement of electromagnetic fields in high voltage transformer substations

This paper presents a helpful approach for evaluation of electric and magnetic fields inside 400/110 kV, 110/10 kV and 35/10 kV transformer substations. Due to the fact that the geometry of the substation elements is complex, it was necessary to apply a three-dimensional approach to the computation and analysis of the electromagnetic field. Computations of electromagnetic fields were conducted for quasi-static states of electrical values at a power frequency of 50 Hz. Results of the performed calculations are good enough compared to the complex and expensive measurements according to Croatian regulations.
