  • Instrument Safety Factor of Current Transformer

    Apr 19, 2018Assume that the fault current is 6 times the rated primary current of CT i.e. 6×2000 A. In this case, if the ISF value of CT is 5 then it is most likely to saturate and hence the secondary current of CT metering core will become zero. Thus there will not any flow of current through the connected meters during such fault.
