- The effects of transformers on the types and characteristics of voltage sag are also different when the voltage sag is transmitted by the transformers, which have different winding connection modes. In this paper, using the system simulation model built by PSCAD, based on the derivation of voltage transfer matrix of transformers with different winding connection modes. Then, taking the Y0/Y-12 type transformer as an example analysed the propagation characteristics of voltage sag caused by single line-to-ground fault, line-to-line fault and double line-to-ground fault. The transfer law of voltage sag propagation of transformers with different winding connection modes is summarized. These laws provide some reference value with on line monitoring, type identification, source location of voltage sag and state evaluation. Industrial plants could reduce the harm caused by the voltage sag reasonable by the way of changing winding connection modes of transformer.
