    Protection CT - Choosing a CT based on your Max Fault Current

    Thank you very much for the info Scott - just a quick question for you: If the knee point is measured @140V with I=0.124A giving the measured CT burden at 17.36VA. As the CT is rated at a 30VA burden - is it safe to estimate that the CT can handle a current 34.56 times the Primary (20 *...

    Good Afternoon, I need help in determining whether the CT we have meets the fault requirements. The CT is a 1000:5 5P20 30VA Protection CT - I have a saturation curve with a knee point at 140V. Rct (Secondary Winding res.) = 0.245 @75C The max fault I need to design for is 32 kA. I understand...
