The results of a comprehensive study of transient overvoltages on a UHV transmission network are presented. In the study, the expected magnitudes of switching overvoltages due to the energization and reclosing, operations were evaluated for a conceptual 1500-kV system. Fault initiation and fault clearing overvoltages were also studied. The sensitivity of(More)
Transformer saturation is an area of major concern as the transformers are designed to run near peak magnetizing flux value and if voltage/frequency (V/f) ratio increases, it may cause the transformer to reach into saturation, which can affect normal operation of the transformer and even cause mal-operation of the protective equipments. This paper explains(More)
