While starting a high capacity motor, it takes 6 times the
full load current. Why it doesn't trip relay or CB's in
that network?

Answer Posted / sunthosh080
usually when you see the relay technical details there will
CLASS type (5-30)
When your motor is taking 6 times for 5 sec you have to
select 5. So that your relay doesnt trip during this and it
depends on the application also.
If it fan application , then it would be around 15-20.
If the relay is tripping during motor starting then it
CLASS problem.

1)we have 1000 cfm Blower,Dia-1Mtr,Velocity of air 94 m/s 2)We have Natural Air velocity 94m/s 3If i Put Wind Mill in natural air ,speed is 94m/s Then it will generate Assume 100kw 4)If i put same wind mill across the Blower,air speed is same 94m/s now the Question is Will it generate 100 kw?
