Annotation of standard text IEC 60255-1-ed.2.0 :
IEC 60255-1:2022 specifies common rules and requirements applicable to measuring relays and protection equipment, including any combination of equipment to form a distributed protection scheme for power system protection such as control, monitoring and process interface equipment, to obtain uniformity of requirements and tests. This document covers the main technologies in use today; other emerging technologies present specific EMC and safety issues but the philosophy in this document will be applied. This second edition cancels and replaces the first edition published in 2009. This edition includes the following significant technical changes with respect to the previous edition: a. scope of document clarified; b. merging units and communications as an integral part of the protection added; c. binary output clarification expanded; d. environmental operating conditions added (Annex B); e. test reference conditions added; f. multiple changes to improve understanding across most clauses; g. derating by manufacturer added; h. safety and EMC tests removed from document and referenced only; i. relay setting and type test guidelines modified (Annex A) j. battery monitor port and low power instrument transformers added. lEC 60255-1:2022 specifie les exigences et les regles communes applicables aux relais de mesure et aux dispositifs de protection, y compris toute combinaison de materiel pour former un systeme de protection distribue pour la protection des reseaux dalimentation, tel que des dispositifs de commande, de surveillance et dinterface de processus, afin dobtenir luniformite des exigences et des essais. Le present document couvre les principales technologies utilisees actuellement. Dautres technologies emergentes presentent des problemes de CEM et de securite specifiques, mais la philosophie du present document est appliquee. Cette deuxieme edition annule et remplace la premiere edition parue en 2009. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a. clarification du domaine dapplication du document; b. ajout des concentrateurs et des communications en tant que partie integrante de la protection; c. extension de la clarification des sorties binaires; d. ajout des conditions denvironnement de fonctionnement (Annexe B); e. ajout des conditions de reference pour les essais; f. apport de modifications multiples qui visent a ameliorer la comprehension a la plupart des articles; g. ajout du detarage par le fabricant; h. suppression des essais de securite et de CEM du document, auxquels il est seulement fait reference; j. modification des lignes directrices relatives au reglage des relais et aux essais de type (Annexe A); k. ajout de lacces de surveillance de batterie et des transformateurs de mesure de faible puissance.
