摘要：

If current transformer (CT) characteristics are not properly selected for fault conditions, saturation will occur and relays can misoperate. To help protection engineers select the appropriate CT, the IEEE published two documents on CT performance and application. This paper compares the guidelines in these two documents and suggests modifications that will make CT selection easier and more realistically estimate CT time-to-saturation.
