This information is essential for users when a specific transformer has to be moved to a different location The transformer vector group is indicated on the Name Plate of transformer by the manufacturer. The vector group indicates the phase difference between the primary and secondary sides, introduced due to that particular configuration of transformer windings connection. The Determination of vector group of transformers is very important before connecting two or more transformers in parallel. If

14/07/2010 · hey first i want to describe the general information abt the vector groups. The vector group of a polyphase power transformer indicates its windings' configurations and the difference in phase angle between them. Three phase transformer can be connected in variety of different ways such as in star, delta, V or zigzag. In many cases, vector diagrams of the primary and secondary e.m.f.s are useful to describe the characteristics, advantages and disadvantages of a given type of connection.

Vector group is important when you run the transformers in parallel. One of the criteria for parallel run of transformers is that the transformers to be run in parallel have to be of same vector group. If you do not have the intension to run it parallel with any other transformer, it should be ok to go for YNyn0. The vector group provides a simple way of indicating how the connections of a transformer are arranged. In the system adopted by the IEC, the vector group is indicated by a code consisting of two or three letters, followed by one or two numeric digits.

How to Determine Transformer Vector Group A vector group is the International Electrotechnical Commission (IEC) method of defining high voltage (HV) and low voltage (LV) winding configurations of three-phase transformers. vector group has a different zero sequence impedance, resulting in different fault currents. Only certain types of cores are recommended for the wye/wye connection.
