ELIMINATION OF ELECTROMAGNETIC INTERFERENCE IN TRANSFORMER STATION
KOMUNALNA ENERGETIKA / POWER ENGINERING, 15
The paper presents maximum values calculations of electric and magnetic fields intensity, emitted by TS 10(20)/0.4 kV, 3x1250 kVA, obtained in software package EFC-400 that allows the simulation in three-dimensional space. Calculations of effective values of the magnetic flow density (magnetic induction) and analysis of electromagnetic compatibility are obtained for height of 4.5 m above the ground surface, in the x-y plane, in parts of offices located above the substation, where the highest levels of the field intensity are expected, with a maximum current load at some equipment pieces. This load rarely appears in real operation, so the calculation results are on the side of safety. Substation is modelled without walls and other obstacles that significantly affects on the reduction of the electric field intensity. In this way, the results of the electric field intensity are largely on the side of safety, since an external wall of transformer stations damping down the same field on negligible values. These values can be verified by measuring on the substation location. The results are shown in diagrams that describes the 2D and 3D distribution of the magnetic flow density and electric field intensity, in the continuous distribution and using isolines. Recommendations for a new model of substation which realizes the reduction of electromagnetic interference are given.
