변압기의 단락강도 시험 시 ANSI와 IEC 규격에 의한 시험 전류의 비교 연구

The Study of Comparison of the Symmetrical Short Circuit Test Current with ANSI/IE Transformers.

Transformers together with all equipment and accessories shall be designed and constructed to withstand the mechanical and thermal stresses produced by external short circuit which include three phase, single line-to-ground, double line-to-ground and line-to-line faults etc. Generally the Short Circuit Test of transformers is tested according to the ANSI/IEEE, IEC/JEC, KS etc, in domestic. In this study, it will be showed and compared the difference of symmetrical current for short circuit test of a Pad -mounted transformer according to with ANSI /IEEE and IEC.
