Calculation of transformer internal faults in short circuit analysis
2008
This paper presents a novel method of modeling internal faults in a power transformer. The method leads to a model which is compatible with commercial phasor-based software packages. Consequently; it enables calculation of fault currents in any branch of the network due to a winding fault of a power transformer. These currents can be used for evaluation of protective relayspsila performance and can lead to better setting of protective functions.
