We are stuck with a situation where protection CTs (class 10P10, 10VA, 500/5) are used for metering - is this a problem?
The 500/5 amp ratio is too large for our current readings, we want use interposing/ratio correction CTs such that our metering is at 200/5 amp scale. What considerations do I have to follow to specify this ratio correction CT?
