Transients in No-Load Condition of Power Transformer 20/0, 4 kV
Innovative approach in power system transient analysis is presented in the paper, applying a new proposed method to process data obtained from processor built in modern protection power relays. The transients, described here appeared precisely while turning the power transformer on and setting it in the no-load condition. The analyzed power transformers 20/0, 4 kV are installed to meet the auxiliary needs of the transformer substation TS 110/20 kV Osijek-4 with electric power.Time response graphic presentations of main power parameters and Fourier analysis of higher harmonics are presented in this paper.
