At our site, we have two 70 hp motors that are feed from a "Step up/Step-down" conception in order to reduce voltage drops. The "Step-up" is done by three single phase transformers (347/2400V 167kVA) connected as a three phase transformer (600/4160V 500kVA). The step down is done by three single phase transformers (347/2400V 167kVA) connected as a three phase transformer (4160/600V 500kVA). I was thinking of buying a 175kW genset that would feed the loads when power losses occurs. But I was wondering if the inrush of the transformers (12 times nominal current at 0.1sec) would mean that I'd have to oversize the genset in order for it to handle the inrush of the transformers. Would I have also to oversize the genset's protection (breaker) as well ?
