| Abstract: | This article analyses the flux paths of a 3-phasc 3-limb transformer and gives a mathematical modelof a 3-phase transformer inresh calenlation Based on the calculation result analysis, the kalman filteringtheory is used to fulfil the digital harmonic restraint transformer differential protcction. Affer rumming ina Cormputer Relay Hardware System, the protection shows: it can trip a transformer fault fast, undgives good restraint during the megnetising inrush or overxcitation of a transformer. |
