Abstract--Protective systems require a faithful reproduction of primary current on the Current Transformer (CT) secondary side. Saturation is a common problem in a steel core CT. Saturation problem causes dreadful effects in the protection systems.
While often considered a minor overhead function, measuring and controlling the currents in a power supply can easily become a major contributor to the success or failure of a design. To aid in achieving optimum solutions for this task, this topic w
