| Learn the essentials of transformer connections – vector groups. The course starts with the vector and phasor basics and their difference. What phase shift and phase angle are and how phase shift is created in a transformer are covered in detail in the following lessons. The course consists of 15 lessons and 1h 26 min. total duration. You will learn why transformers are connected to form specific vector groups, the delta and star connections, and the relationship between line and phase voltages and current. What are the advantages and disadvantages of connecting transformer winding in Star or Delta? The answers are covered in great detail. We will discuss the 26 MVA transformer nameplate. The course continues with defining vector group dy11, clock method, lead and lag concepts. Finally, you will learn to draw vector group and connections of dy11,dy1, yd1, yy0,dd0, yy6, and yz1 configurations. |
