Answer / ashish khamparia

for C.T. rating we should have motor rating in kw. so that
we calculate the load.

Answer / vijyesh bhatt

depend of moter kw rating

Answer / sandeep

DONT ASKS INCOMPLETE QUESTIONS MR.KUMAR.

Answer / padmanabha prasad

CT range depends on the fullload current of the motor not
voltage. So first find out the motor FLA and based on that
u can select the range of CT(metering). Range should be 0
to FLA*20%)

Answer / soewinaung

We must know full load ampere of the motor.If we know ,we
can select C.T. as their ratio to show on ammeter. It is
best to use ammeter selector to know ampere on each phase.

Answer / engr, abdul barek

Mr. Naresh: Motor rating is always kW and transformer rating is KVA.

Alternator no depends on power factor.

For CT design, Should be need KW & voltage lavel.

Answer / virendra

Rating of CT means maximum carrtent to be measure for that
voltage , powerfactor & Wattage capacity is required.
depending upon that you can calculate the total current to
be measured & also the rating of the current transformer

Answer / peter desoza

P=1.732 VI X.85
= 1 amp APPROX
NO NEED CT, because the main purpose of CT is to step down
the current,U CAN USE SIMPLE AMPERE METER OK

Answer / naresh

we should know the kva rating of the motor & also power
factor.
