Abstract :
This paper presents the correlation of voltage sags between two sides of difference types of transformer winding connections. We study the propagation of voltage sag down to low voltage and reverse up to high voltage. This study performs on network of provincial electricity authority (PEA), a utility in Thailand. The network is modeled using PSCAD/EMTDC. The faults are applied on this network to generate voltage sags. The types of transformer winding connection are varied to study its influence on voltage sag. Finally, the results are discussed.
