Answer / will

For PT -Designed on Nominal voltage
For CT- Total designed load current, moreover CT shall be
designed to bear the Momentary SC Current.

Answer / dinesh kumar

I decid CT rating acording current and PT acording Voltage.
if current flowing in cable apox 300 amp and my ammeter
rating is 5 amp. than we will use CT rating of 60/1. similr
PT. But we mind that current of cable could be increse any
time thn 60/1 CT will be fail.

Answer / kishor mahale

In LT current is more and HT voltage is more. So for high
current CT can be used and for high voltage HT can be used.

How you calculating the current for a 2.5 Sqmm cable. A 30 Hp 3 phase AC motor of power what size of cable is used for this motor.
