WebMay 11, 2024 · DC component of fault current will not cause CT saturation if the following criteria is satisfied [1]. For example, consider a circuit with 20,000A of fault current and X/R of 10. Assume CT ratio is 600:5 and burden resistance R of 1.5Ω. Using the above equation, to avoid DC saturation the CT knee voltage has to be above 159V. WebJun 26, 2024 · The Standard also recognizes this when it says that the rated primary current of a CT can be 10, 12.5, 15, 20, 25, 30, 40, 50, 60, 75A and their decimal multiples or fractions. But, when it comes ...

WebAug 11, 2024 · The reason for this is that a given secondary current requires more voltage from the ct for a higher burden, and the core flux density is proportional to the time-integral of this voltage. When the core becomes saturated, significant current is diverted through the cts magnetizing branch, and the desired secondary current is reduced and distorted.
