  If a transformer is comprised of three identical single-phase units, is the impedance of any one transformer on its own base, and is three times the rated power of one transformer. For a delta connection, line-to-line is the rated coil voltage of one transformer. For a wye connection, line-to-line is the rated coil voltage multiplied by . Step 4.

  Jul 08, 2009 · a. Connect 3 phase transformer primaries in delta. Do not use wye primaries except in special cases because of “problem connections”. b. When wye primaries are used, special consideration must be given to the grounding connections and the type of core/coil construction to prevent tank overheating, as well as voltage and load balance problems.

  Transformer connections often introduce a phase shift between high- and low-voltage currents. Proper CT connections compensate for this shift. For a delta-primary, wye-secondary transformer, CTs are normally wye connected in the primary and delta connected in the secondary.
