About this document
Zigzag Transformers for Harmonic Reduction by pd110382 is a document available to read on EtoBox.
The document discusses two schemes that use zigzag transformers to reduce current harmonics in a distribution system. Scheme 1 installs a zigzag transformer between the transformer secondary lines and neutral. Scheme 2 installs it between the secondary lines and a three-phase diode bridge rectifier. Both schemes significantly reduce current harmonics as shown through simulations. The zigzag transformer provides a path for zero-sequence currents, sharing the neutral load current to reduce overheating.
