Mr.Ramesh kumar said answer is very correct..

We cannot use the Measuring C.T. for the protection
purpose.and we also cannot use the protection C.T. for
Measuring purpose.

Protection C.T Classes are:
CL 5P20
CL 5P10
CL PS

Measuring C.T Classes are:
CL 0.2
CL 0.5
CL 1.0

Generally the Measuring C.T's and Protection C.T's are
differentiate by using the C.T Classes..
