We are using Single phase power transformers connected in Delta / Star (3-phase bank) as Generator Step Up transformers. We rewound one of those and the winding capacitance for this rewound transformer is almost 50% higher than existing other two transformers. Will it be any impact on the performance, if the transformers with unequal winding capacitances are connected in Delta / Star for a star winding generator of 210MW capacity? All other parameters are matching with existing transformers.
