TC 95 - Measuring relays and protection equipment
Standardization of measuring relays, protection equipment and protection functions embedded in any equipment or systems used in various fields of electrical engineering covered by IEC, including combinations of devices and functions which form schemes for power system protection. TC95 scope includes control, monitoring, and process interface related functions and equipment used with protection systems (such as automatic reclosing, fault location, teleprotection or process data interfaces, and fault recording); as well as protection and protection related functions of distributed energy resources (DER) or inverter based resources (IBR). The concepts and definitions described in the standards developed by TC95 are intended for all power system protection engineers, dealing with the various activities related to protection functions and protection relays. These include specification of functional and product design requirements and design qualification type tests. These requirements and type tests can be used with interpretation for FAT (Factory Acceptance Tests), SAT (Site Acceptance Tests), commissioning and maintenance tests. Excluded from TC 95 scope are the following: All devices covered by standards within the scope of other IEC Technical Committees, for example instrument transformers (TC 38).
Relais de mesure et dispositifs de protection
Normalisation des relais de mesure, des équipements de protection et des fonctions de protection intégrés dans tout équipement ou système utilisé dans divers domaines du génie électrique couverts par l’IEC, y compris les combinaisons de dispositifs et de fonctions qui forment des plans de protection du réseau électrique. Le domaine d'application du TC95 comprend les fonctions de contrôle, de surveillance et d'interface de procédé, ainsi que les équipements utilisés avec les systèmes de protection (tels que le réenclenchement automatique, la localisation des défauts, la téléprotection ou les interfaces de procédés et la perturbographie); de même que la protection et les fonctions de protection associées aux ressources énergétiques décentralisées (DER) ou aux ressources issues de convertisseurs électroniques (IBR). Les concepts et définitions décrits dans les normes développées par TC95 sont destinés à l’ensemble des ingénieurs protection des réseaux électriques, traitant des différentes activités liées aux fonctions de protection et aux relais de protection. Il s'agit notamment des spécifications d'exigences fonctionnelles et de conception du produit ainsi que des essais de type, de qualification ou de conception. Ces exigences et essais de type peuvent être adaptés pour les tests FAT (Factory Acceptance Tests), SAT (Site Acceptance Tests), les tests de mise en service et de maintenance. Sont exclus du champ d'application du TC 95, tous les dispositifs couverts par des normes entrant dans le champ d'application d'autres comités techniques de l’IEC, par exemple les transformateurs de mesure (TC 38).

The International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for electrical, electronic, and related technologies. Founded in 1906, the IEC provides a global platform for companies, industries, and governments to meet, discuss, and develop the international standards they require.
A Technical Committee (TC) in IEC is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
