go to the Distribution transformers product page Graham Norman asked on Apr 9th, 2014 in Distribution transformers

We have a ABB, 6-pulse harmonic transformer, 750 KVA, 60 HZ. Input: 4160 V, 3-phase; output: wye-600 V, 60 HZ, 3-phase, 361 A. Delta-600 V, 3-phase, 361 A.

Can I parallel secondary windings (wye to delta) to get my full capacity(750KVA) from this transformer to operate a 600Hp fan motor.

ABB's answer

It is not possible to parallel the two LV windings as they have been connected in a delta and wye configuration, meaning that there will be a 30 degree phase shift between the respective voltages.

To parallel the windings would cause the transformer to fail and be considered an unsafe act.
