What will happen if i connect two 3-phase tranformers secondary supply on one bus bar that is R-Y..

Answer / pabba praveen

Voltage ratio, polarity and phase sequence of both the
transformers should be same for parallel operation Relative
phase displacement between the two transformers should be
zero. Load will be shared based on the percentage impedance
of the transformer.
