current transformer cannot measure voltage or not ? then y
we use P.T ?
Answer / tupe ganesh
current transformer has least no. of turns and thicker gauge so potantial diff maintainig is low so vtg across the ct has very small in mv and current is large due to large area and less resistance
in pt has large no of turns and maintain potantial diff large as resistance is more current is very small
