directional comparison protection
overreach protection, usually not a distance protection, using telecommunication, in which the relative operating conditions of phase angle measuring elements, at each end of the protected section, are compared using a locally derived voltage or current as a reference
Note – In the USA, the term "directional comparison protection" is applied to any non-unit protection using telecommunication, with or without overreaching or underreaching distance protection.

protection à comparaison directionnelle
protection à portée étendue et à liaison de transmission, qui habituellement n'est pas une protection de distance, dans laquelle les conditions de fonctionnement relatives des éléments de mesure d'angle de phase à chaque extrémité de la section protégée sont comparées, en utilisant comme référence une tension ou un courant obtenus localement
Note – Aux Etats-Unis d'Amérique, le terme anglais "directional comparison protection" est utilisé pour toutes les protections à sélectivité relative de section et à liaison de transmission, qu'elles comportent ou non une protection de distance à portée étendue ou réduite.
