of the electrical power system. At the time of transformer energization high current is drawn by the transformer known as the inrush current. This current is nearly ten times more than the full load current of transformer. It produces mechanical stress on transformer and also affects the windings and bushings of the transformer. The large switching transient current affects malfunction of protection system of power system and the different equipments connected to system. So the inrush current should be minimized. There are different methods used to minimize the inrush current such as volt second balance, series compensator, point on wave switching method etc. This paper focuses on point on wave switching method. It also explains the results for inrush current of three phase transformer with and without point on wave switching method. A test is driven on 450 kVA, 500kV/230kV grounded Y/D transformer in MATLAB/SIMLINK environment. It also focuses on

输入的影像可以是一个复杂的形象contaning点，纹理，缺陷等图形用户界面可以让用户手动识别中心，动态更新和纪念中心。标志着该中心可以在整个图像或它的一部分。一旦所有这些中心鉴定，RDF是由程序计算和策划，并包含一个txt文件保存中心的名单。(The input image can be a complicated image contaning dots, textures, defects etc. The GUI lets the user manually identify the centers, dynamically updating, and marking the centers. The centers can be marked in the whole image or a part of it. Once all the centers are identified, the RDF is calculated and plotted by the program, and a txt file containing the list of centers is saved. )
