My requirement is 1VA,50/5A Current Transformer for
Metering .If I select 15VA , 50/5A CT.Is there any
possibility of Technical Problem ?
Answer Posted / anbuselvan
No problem.
Bcaz CT is an Instrumental Transformer(i,e.,Measurement of
High rating current) to measure only Current.
So there will be no of tapping for each range of current.So
that it will easily sense the rating which u set.
Here both your current rating is same.so no problem at all,
even if the voltage varies.

What are the material used for resistor?
A 500 V shunt motor runs at its normal speed of 250rpm when the armature current is 200A. The resistance of the armature is 0.12 Ω. Calculate the speed when a resistance is inserted in the field reducing the shunt field to 80% of normal value and the armature current is 100A.
