Answer Posted / tahir vora- reliance jamnager-
5P10 means the maximum permissible limit of error (accuracy limit) is 5% at 10 times rated current (Accuracy Limit Factor). CT will give ratio error of only 5% even if fault current reaches 10 times the nominal value (In), after that CT will start to saturate.
