The Study of Characteristics evaluation of short-circuit tests for Power Transformers

변압기 단락강도시험 성능평가에 관한 고찰

Power transformer shall be designed and constructed to withstand the mechanical and thermal stresses produced by external short circuits which include three-phase, single line to ground, double line-to-ground, and line-to-line faults on any one set terminals at a time. This paper presents the method of short-circuit test and means of evaluation during and after each test to judge the results of short-circuit tests.
