What is a Transformer Vector Group?

A transformer vector group tells how the windings are connected. It also indicates the phase difference between the primary and secondary sides.

ComponentDescription
Primary WindingThe coil connected to the power source
Secondary WindingThe coil connected to the load
Phase DifferenceThe angle difference between primary and secondary voltages

Importance of Selecting the Right Vector Group

Choosing the correct vector group ensures proper system operation. It helps in achieving desired voltage levels and phase shifts.

  • Improves system reliability
  • Ensures proper load sharing
  • Prevents transformer damage

Types of Transformer Vector Groups

There are several common vector groups. Here are a few:

  1. Dyn11: Common in distribution transformers
  2. Yyn0: Used for grounding purposes
  3. Dy5: Often used in industrial applications
