Over the past several years, there have been major technological advances in the area of fibre optics links and digital communication systems. This opens the possibility for digital teleprotection systems which are both faster and more reliable than current analogue ones. This paper presents a description of a generic Digital Teleprotection Unit (DTU) followed by a discussion on the technical characteristics of current commercial systems. A comparison is made between DTUs and their analogue counterparts in the area of transfer trip delay. Finally, a direct transfer trip system utilizing redundant DTUs is proposed.
