  • 501B - CT Secondary Loop Tester The best way to test CTs in service is to use an admittance tester. The admittance test can be quickly performed even with 50Hz/60Hz current in the primary, and is a very sensitive means of detecting shorted turns and various other faults in CTs. The admittance test will find every fault except a high resistance joint.
