Answer Posted / pillay
D.G if ac is rated in KVA.Usually the alternator is rated at 0.8 pf. So KW/PF=KVA. 110/0.8=137.9.KVA.
Now the D.G must have some spare power to take care of starting current and a bit of future expansion so we load the D.G at 75%.
137.9/.75=183.8KVA
Now you can buy the nearest available D.G in the market.
Maybe 175KVA or 185 KVA
