Abstract: Current transformer saturation can cause differential protective relay mal-operation. This paper presents a technique for overcoming current tramsformer saturation problem based on the measurements of the fundamentals' phase-angles of the secondary currents on both sides of the protected object. Mal-operation could be avoided by introducing these measurements to the phase comparison technique which has the ability to distinguish between internal and external faults..
