About this document

Paralleling Transformers and Phasing Guide by Ben Wee is a document available to read on EtoBox.

1) Phasing is determining if the voltages on two electrical systems are in the same phase before paralleling them. This involves verifying the voltages between corresponding phases are nearly zero. 2) Standard transformer connections have phase shifts of either 0 or 30 degrees between primary and secondary voltages. Non-standard connections can have other phase shifts. 3) Four common phasing situations are described: two systems in phase, a 120 degree phase difference caused by a transformer or tie swit
