Which current transformer is more accurate?

There is the 0.15 class which is more accurate than the 0.3 class although this class is not often referenced anymore.

Lastly, the IEEE standard defines the 0.15S class which is the highest recognized accuracy class. An accuracy class means that a CT will meter current to within plus or minus that amount.
