Abstract

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..
