Le document SIST EN IEC 62052-31:2025, qui se concentre sur les équipements de comptage de l'électricité, établit des exigences générales de sécurité ainsi que des tests pour les compteurs de courant alternatif et continu, directement connectés ou fonctionnant avec des transformateurs ou des transducteurs. Son champ d'application est suffisamment large pour englober une variété d'équipements, allant des compteurs à ceux destinés à la gestion de l'énergie électrique sur des réseaux électriques jusqu'à 1000 V AC ou 1500 V DC. L'un des points forts de cette norme est son approche structurée en matière de sécurité, puisqu'elle spécifie clairement les conditions appropriées pour les tests de type. Cela garantit que seuls les équipements respectant des critères de sécurité rigoureux atteignent le marché. De plus, le fait que la norme englobe des compteurs avec des affichages intégrés ainsi que des affichages détachés est particulièrement pertinent pour les fabricants, car cela leur permet de concevoir des produits adaptés aux différentes exigences des utilisateurs finaux. En outre, la norme traite également des circuits d'entrée et de sortie auxiliaires, des indicateurs de fonctionnement et des sorties de test, élargissant ainsi sa portée pour inclure non seulement les mesures de l'énergie électrique, mais aussi les aspects de fonctionnement et de contrôle. Cela renforce sa pertinence dans le contexte de l'évolution des dispositifs de mesure qui intègrent des fonctionnalités additionnelles. Il est également à noter que la norme exclut des équipements tels que les compteurs destinés à fonctionner avec des tensions supérieures aux seuils définis, ce qui aide à affiner son application et à se concentrer sur des produits qui sont réellement concernés. Cela permet de s'assurer que les exigences de sécurité restent ciblées et pertinentes pour les utilisateurs expérimentés, tout en prenant en considération l'installation et l'utilisation normales par des personnes non qualifiées. Enfin, la révision technique apportée dans cette deuxième édition confirme non seulement l'engagement à mettre à jour les exigences en matière de sécurité, mais aussi à répondre aux défis actuels et futurs des technologies de mesure de l'énergie. La norme SIST EN IEC 62052-31:2025 est donc un outil essentiel pour les fabricants, les installateurs et les utilisateurs, facilitant la conformité réglementaire et la mise en œuvre de solutions efficaces et sécurisées dans le domaine de la mesure de l'électricité.
EN IEC 62052-31:2024 표준은 전기 계량 장비에 대한 일반 요구 사항, 시험 및 시험 조건을 명시하고 있으며, 특히 제품 안전 요구 사항 및 시험에 중점을 두고 있습니다. 이 표준의 범위는 직접 연결된, 변압기 작동 또는 변환器 작동 AC 및 DC 전기 계량기와 부하 제어 장비에 적용됩니다. 이 표준의 강점은 전기 계량 장비가 1,000 V AC 또는 1,500 V DC 전압에서 전기 에너지를 측정하고 제어하도록 설계되었을 때 필요한 포괄적인 안전 요구 사항을 제공하는 것입니다. 또한, 추가 통신 모듈을 포함한 모든 기능적 요소가 단일 계량기 케이스에 장착되어야 하며, 통합 표시기 디스플레이 또는 분리된 표시기 디스플레이와 함께 작동할 수 있는 조건을 규정하고 있습니다. 이러한 포괄적인 접근 방식은 사용자가 전기 계량 장비를 안전하게 사용할 수 있도록 보장합니다. 표준은 또한 저전력 계기 변환기(LPIT)나 센서와 함께 작동하도록 설계된 변환기 작동 계량기에 적용되며, 전기 에너지 측정을 위한 보조 입력 및 출력 회로와 작동 표시기 및 시험 출력을 포함합니다. 안전 요구 사항은 일반적으로 제정된 가정에 기반하여 세워졌으며, 이는 계량 장비가 올바르게 설치되고, 일반 사용자에 의해 사용되며, 정상적인 사용 중에 안전하게 작동하도록 보호 장치가 갖춰져야 함을 명시합니다. 또한, 이 문서는 특정 매칭 소켓에 설치되도록 설계된 장비에 대해서도 요구 사항을 적용하며, 전기 에너지 측정 및 제어에 관한 추가 안전 요구 사항이 필요할 수 있음을 명시하고 있습니다. 그러나 1,000 V AC 또는 1,500 V DC를 초과하는 전압에서 작동하는 계량기와 같은 특정 장비는 이 문서의 적용 범위를 벗어난다는 점에서 유의해야 합니다. 결론적으로, EN IEC 62052-31:2024 표준은 전기 계량 장비의 안전 요구 사항 및 테스트에 대한 포괄적인 지침을 제공하며, 사용자의 안전과 관련된 중요한 요소들을 반영하여 전기 계량기의 안전한 사용과 운영을 보장하기 위한 중요한 기준이 됩니다. 이는 전기세 측정의 신뢰성을 높이고, 전기 관련 시스템의 안전성을 한층 강화하는 데 기여합니다.
The EN IEC 62052-31:2024 standard provides comprehensive guidelines for electricity metering equipment by establishing general safety requirements, testing protocols, and conditions vital for ensuring the reliability and functional integrity of AC and DC electricity meters and load control equipment. The scope of this standard is noteworthy as it encompasses a broad range of metering devices operating within specific voltage limits (up to 1,000 V AC and 1,500 V DC), ensuring safety and performance across various applications in electrical networks. One of the strengths of this standard is its inclusive nature, as it addresses directly connected, transformer-operated, and transducer-operated meters, thus catering to diverse metering architectures. Additionally, it supports integrated and detached display configurations, illustrating its flexibility for installations requiring both types of displays. Furthermore, the document stipulates that all functional elements must be enclosed within a single meter case, promoting safety and operational integrity by reducing the chance of exposure to hazardous parts. Moreover, the EN IEC 62052-31:2024 standard emphasizes the importance of safety for ordinary users, indicating a strong commitment to user accessibility without compromising safety.

Die Norm EN IEC 62052-31:2024 bietet umfassende Spezifikationen zu den allgemeinen Sicherheitsanforderungen und den dazugehörigen Tests für elektrische Messgeräte und Steuerungseinrichtungen. Diese Norm ist besonders relevant für die Entwicklung und den Betrieb von Geräten, die auf elektrischen Netzwerken bis zu 1.000 V AC oder 1.500 V DC messen und steuern. Ein herausragendes Merkmal dieser Norm ist ihre Flexibilität, da sie sich auf verschiedene Messgeräte bezieht, darunter direkt angeschlossene Meter, Transformatoren betriebene und transducerbetriebene Geräte. Ein weiterer wesentlicher Aspekt der Norm ist die umfassende Abdeckung aller funktionalen Elemente, einschließlich der Add-on-Kommunikationsmodule. Die klare Definition der Betriebsvoraussetzungen für integrierte sowie abgetrennte Anzeigeelemente ermöglicht den Herstellern eine bessere Integration in bestehende Systeme und eine vereinfachte Testsituation. Die Norm berücksichtigt auch die Installation der Geräte, die sowohl wandmontiert als auch in spezifisch passende Steckdosen oder Racks eingebaut werden können. Diese Vielseitigkeit macht die Norm besonders nützlich für Anbieter von elektrischen Messgeräten, die innovative Lösungen im Bereich der Energieüberwachung bzw. -steuerung anstreben. Die Sicherheitsanforderungen basieren auf realistischen Nutzungsszenarien und setzen voraus, dass die Messgeräte korrekt installiert sind und in einem Umfeld verwendet werden, in dem auch die Sicherheit der Endnutzer gewährleistet ist. Dabei wird darauf geachtet, dass gefährliche Teile bei normaler Nutzung nicht zugänglich sind, was das Risiko für den Benutzer erheblich senkt. Nicht zuletzt ist die Norm sowohl auf auxilary Input- und Output-Schaltungen als auch auf Betriebsanzeigen und Testausgänge anwendbar, was ihre Relevanz im Bereich der elektrischen Energieerfassung weiter erhöht. Mit dieser Überarbeitung wird die erste Ausgabe von 2015 storniert und durch eine technisch verbesserte Version ersetzt, die aktuellen Technologien und Sicherheitsanforderungen Rechnung trägt.
