Measuring relays and protection equipment - Part 187-1: Functional requirements for differential protection - Restrained and unrestrained differential protection of motors, generators and transformers
IEC 60255-187-1:2021 specifies the minimum requirements for functional and performance evaluation of (longitudinal) differential protection designed for the detection of faults in ac motors, generators and transformers. This document also defines how to document and publish performance test results. This document defines the influencing factors that affect the accuracy under steady state conditions and performance characteristics during dynamic conditions. The test methodologies for verifying performance characteristics and accuracy are also included in this document. This document, together with IEC 60255-187-2 and IEC 60255-187-3, cancels and replaces IEC 60255-13. This document includes the following significant technical changes with respect to IEC 60255-13: a) IEC 60255-13 has been significantly revised to follow the common structure of the functional standards for protection relays (IEC 60255-1xx series). IEC 60255-187-1 has been developed to address the restrained and unrestrained differential protection of motors, generators and transformers. The revisions include detailed description of the functions including the performance specification, testing and documentation requirements.

Relais de mesure et dispositifs de protection - Partie 187-1: Exigences fonctionnelles pour la protection différentielle - Protection différentielle avec et sans caractéristique de retenue des moteurs, générateurs et transformateurs
IEC 60255-187-1:2021 spécifie les exigences minimales relatives à l'évaluation fonctionnelle et à l’évaluation de la performance de la protection différentielle (longitudinale) conçue pour la détection des défauts dans les moteurs à courant alternatif, les générateurs et les transformateurs. Le présent document définit également comment documenter et publier les résultats des essais de performance.Le présent document définit les facteurs d'influence qui affectent la précision en état stable et les caractéristiques de performance dans des conditions dynamiques. Les méthodologies d’essai permettant de vérifier les caractéristiques de performance et la précision sont également incluses dans le présent document. Le présent document, ainsi que l’IEC 60255-187-2 et l’IEC 60255-187-3, annule et remplace l’IEC 60255-13. Le présent document inclut les modifications techniques majeures suivantes par rapport à l'IEC 60255‑13: a. L’IEC 60255-13 a été considérablement révisée pour suivre la structure commune des normes fonctionnelles pour les relais de protection (série IEC 60255-1xx). L’IEC 60255-187-1 a été développée pour traiter la protection différentielle avec et sans caractéristique de retenue des moteurs, générateurs et transformateurs. Les révisions comprennent une description détaillée des fonctions, y compris les spécifications de performance, les essais et les exigences en matière de documentation.
