What it represents
A zigzag winding interconnects portions of phase windings in a specified arrangement. Its neutral and zero-sequence behaviour depend on the actual transformer connection and ratings.
How to read it
- Use the manufacturer's winding diagram to identify all interconnections.
- 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
- State zigzag designation
- Identify neutral point
- Reference earthing or transformer duty
A distinction that matters
A zigzag winding is different from a three-phase star formed from one winding per phase.
