The SIST EN IEC 61869-1:2024 standard outlines essential general requirements specific to instrument transformers designed for higher voltage applications exceeding 1 kV AC or 1.5 kV DC. Its scope is critical as it caters to the needs of applications requiring both analogue and digital secondary signals for purposes of measuring, protection, and control across a wide frequency range of 15 Hz to 400 Hz, including dedicated provisions for DC applications. One of the notable strengths of this standard lies in its comprehensive coverage of the necessary limits of errors concerning both analogue and digital secondary signals. Such detail ensures high levels of accuracy and reliability in instrument transformers, which are paramount in high-voltage and medium-voltage environments. Additionally, it incorporates bandwidth requirements that further enhance signal fidelity, thereby aligning with modern technological advancements in power utility automation. The technical revisions introduced in the 2024 edition reflect a significant advancement over previous iterations, as it merges key elements from IEC 61869-6:2016, thereby harmonizing standards for various transformer applications. The inclusion of new scope definitions and updated classification for special tests, characterized as either type or routine tests, enhances the standard's applicability and relevance in contemporary use cases. With added specificity in terms of commissioning tests and the introduction of new annexes (E, F, G, and I), SIST EN IEC 61869-1:2024 demonstrates a forward-thinking approach that accommodates evolving industry needs. This revision not only replaces the earlier standards published in 2007 and 2016 but also sets a benchmark for future developments in the realm of instrument transformers, emphasizing its critical role in ensuring safety and operational efficiency in electrical systems.
La norme SIST EN IEC 61869-1:2024, intitulée « Transformateurs de mesure - Partie 1 : Exigences générales (IEC 61869-1:2023) », se positionne comme un document essentiel destiné aux transformateurs de mesure récemment fabriqués, répondant à des applications avec des tensions nominales supérieures à 1 kV AC ou 1,5 kV DC. Cette norme s'applique à la fois aux signaux secondaires analogiques et numériques, utilisés à des fins de mesure, de protection et de contrôle dans une plage de fréquences de 15 Hz à 400 Hz, ainsi que pour des applications DC. Une des forces de la norme réside dans sa portée clairement définie, établissant des exigences générales pour les transformateurs de mesure dans des systèmes à haute tension (HT), tout en maintenant des distinctions nécessaires par rapport aux systèmes à basse tension (BT) qui sont couverts par la norme IEC 61869-201. Cette structure hiérarchique permet une compréhension claire des exigences selon les différents types d'applications. De plus, la norme IEC 61869-1:2023 introduit des exigences précises concernant les limites d'erreurs pour les signaux secondaires, qu'ils soient analogiques ou numériques. La normalisation des caractéristiques de l'interface numérique pour les transformateurs de mesure, en référence à la norme IEC 61869-9, témoigne également de la pertinence de cette norme dans le cadre des systèmes de communication modernes et de l'automatisation des utilitaires. L'inclusion de nouvelles exigences relatives à la bande passante, ainsi que la spécification des exigences d'exactitude sur les harmoniques et sur le filtre anti-repliement dans la section 5.7, renforce la capacité de ce document à répondre aux défis émergents dans le domaine des transformateurs de mesure. La révision technique apportée par cette édition, qui remplace la première édition de 2007 ainsi que l'IEC 61869-6:2016, et qui introduit des modifications conséquentes, telles que la classification de nouveaux tests spéciaux et des tests de mise en service, témoigne de l'engagement constant à améliorer la sécurité et la performance des équipements fournis. Enfin, les nouvelles annexes (E, F, G et I) enrichissent le contenu du document et apportent des précisions supplémentaires qui sont d'une grande aide pour le développement et le déploiement des transformateurs de mesure. La norme SIST EN IEC 61869-1:2024 se distingue donc par sa pertinence, son exhaustivité et ses spécifications détaillées, positionnant les transformateurs de mesure d'aujourd'hui pour faire face aux exigences techniques contemporaines.
