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.
