500			_aABSTRACT Whenever fault occurs at any stage of power system, the magnitude of voltage and phase angle both are changed. In distribution system, there are sensitive load s such as digital computers motor drives etc are connected with a system. Due to fault conditions, unbalancing in voltage may occur. So it may cause of damaging of equipment. Fault in distribution system may lead to voltage dip in system; it is the big problem of power qual ity. So it more important to understand the power quality and it is also important to analyze voltage dip propagation on different types of faults and by the changing of transformer winding connections. The work of this study is on CIGRE low voltage distribution network, main focus of this research study is to voltage dip propagation and also comparing of simulation results with mathematical calculation s. Dip propagation is major problem in power network and creates power quality PQ problems. This work is done on the Test network CIGRE (International council of large Electric system) Low voltage Distribution Network. This network was proposed by CIGRE working group in their meeting held in Geneva in order to study the European network, with the large scale, integration of renewable energy.
