IN MY INDUSTRIES 125 HP MOTOR USED FOR THAT ONLOAD AMPS UP TO 280 SO CAN I USE ONE LOWER KVA DG S..

Answer / sudhakar g

Generally if u take125HP if we converted in to KW it will come 93.75KW only we can use...

I=(93.75*1000)/(1.732*415v*0.8)

I=163A

this is the maximum current we can use at full Load then how you are using upto 280A....

I think it is not possible...Correct me if i am wrong...

In your second case it is not possible To genrate 125KVA DG set to 250KVA Stepup transformers bcoz if we saw in Generation or transmission of supply the 400KV or 200KV lines there we can use 3 MVA transformers for stepup or Stepdown bcoz the input sully is capable to genrate the supply higher or lower......
According to IS standards the distance between pits must be
2.5mtrs and from the building it should be far from 3000mm
