Answer / ramesh

1 Hp = 746 watts
10 Hp Motor
10*746=7460w
so 7460 w is the power drawn by 3-ph motor. and three phase
voltage is 415 voltage.

so I = P/root3*v*pf*eff
i=Wattage/1.732*415*0.8*0.85
=7460/1.732*415*0.8*0.85
=7460/489
=15.25A

Answer / ramesh herur

The current drawn is Approx 16 Amps

Answer / karthik.j

10HP = 10*745watts = 7.45kW
I = 7.45/(1.732*415(volt)*0.8(power factor)*0.8(efficiency)
= 16.19Amps

Answer / pillay

how much current a 3 ph 10 hp motor takes is depending
on the load it is carrying. Genarally the max
safe current for a motor rated as 10 hp at
440 volts is about 14 amps.If it is consuming less
than 14 amps, that means it is under loaded but if it is
carrying more than 14 amps than IT MEANS IT IS OVERLOADED
which is harmful for the motor.

Answer / thalha

3ph 10HP full load current is 13.5...
load current is taken only how the load is connected..
We use star/delta starter mean running current is low than DOL starter...

Answer / bala.a

Laod = 10 HP = 10 * 0.746 =7.46 KW
= 7.46 * 1000 / RT 3 * 415= 10.38 A
Consider 1.6 Time for starting current = 10.38 * 1.6 =
16.06 A

Answer / emitparmar

10 Hp Motor....
1 Hp = 746 watts..

so 7460 w is the power drawn by 3-ph motor. and three phase
voltage is 415 voltage.

so I = P/V,
= 7460/415
= 17.97 A

Can u explain : how capacitor act when the supply is given is a.c and d.c. I know that when d.c supply is given then the capacitor charges and becomes open circuited. But please say about when a.c is given. I have seen that when a.c supply is given ,it charges and discharges, But when we plug in capacitor to our daily supply and take it out ,then we join those wires spark will appear,which seems charge is present ,but when a.c is given it should charge and discharge
