What it represents
A star-zigzag transformer combines a star-connected winding set with a zigzag-connected set. Its winding arrangement and neutral duties require the manufacturer's complete connection designation.
How to read it
- Read the zigzag terminal arrangement from the selected transformer diagram.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.
Information to show or reference
- Record connection designation
- Identify neutral terminal
- Reference winding ratings
A distinction that matters
A zigzag connection is not another spelling of a simple star winding.
