Sažetak
A quasi-static analysis of an oil-type distribution transformer was described to determine the ambient magnetic field in the surrounding region. Windings and terminals were assumed to be primary sources of the magnetic field. Core and tank of the transformer were modeled by secondary sources (surface current density, surface charge density and eddy current density). In order to find these sources, the system of integral equations was transformed into linear system. Magnetic field was calculated by evaluating volume and surface integrals. The calculated and measured results of the magnetic induction were compared on a 630 kVA transformer. Evaluation of the magnetic induction was made for distribution transformers in the range 50-2500 kVA.
