ZigZag Transformer Applications for Harmonic Attenuation

Share

Passive harmonic attenuation can be accomplished by using specialty magnetics including medium-voltage dry type transformers.  This presentation will review a case study of the dry type transformer design for a substation upgrade which featured a double-zigzag secondary winding, with a 30-degree phase shift between outputs to mitigate 5th, 7th, 11th and 13th current harmonics.  The overview will include a detailed analysis of the harmonic cancellation effects of a zigzag transformer connection.
