The paper presents an automatic procedure for quantitative evaluation of energizing inrush current of a specific range of single phase power transformers: 1.2-25 kVA. Starting from transformer main rated data and core magnetic H-B characterization, the first peak value of inrush current is accurately estimated. Additionally, the harmonic content of its waveform is also investigated offering valuable indicators of this transient phenomenon. The predetermination of the main inrush current… CONTINUE READING
