Supposing I have 3phase power installation, 80A/phase, with 420V/phase as well, what is the calculation for generator to be installed as standby?
generator capacity always in KVA Your Connected Load = 1.73*420*80/1000=58KVA Approx.
You have to choose DG Capacity =62.5KVA If your power installation operation in full phase,ok
