fellow experts, i would like to solicit ideas regarding accuracy of current transformer for revenue metering use. the case involved the CT operating at an intermittent open-circuit condition due to a "snipped" conductor at the terminal block (say test block). i have already tested the CT using a specified testing equipment for metering instruments and have met the required values stating that the CT is still in good condition. however, my gut tells me to do otherwise that is to not re-install the CT. i want to perform another test but i dont know if what i am going to do will be justifiable since i have not seen the procedure in any written literature. hope the experts here could enlighten me with this problem. thank you.
