Lightning protection system components (LPSC) - Part 3: Requirements for isolating spark gaps (ISGs)
IEC 62561-3:2023 is available as IEC 62561-3:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62561-3:2023 specifies the requirements and tests for isolating spark gaps (ISGs) for lightning protection systems. ISGs can be used to indirectly bond a lightning protection system to other nearby metalwork where a direct bond is not permissible for functional reasons. This third edition cancels and replaces the second edition, published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition. a) alignment with the latest edition of ISO 22479 relating to humid sulphurous atmosphere treatment; b) addition of a new normative Annex D for the applicability of previous tests.

IEC 62561-3:2023 est disponible sous forme de IEC 62561-3:2023 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 62561-3:2023 spécifie les exigences et les essais applicables aux éclateurs d'isolement destinés aux systèmes de protection contre la foudre. Les éclateurs d'isolement peuvent être utilisés pour raccorder indirectement un système de protection contre la foudre à une autre partie métallique proche lorsqu'un raccordement direct n'est pas admissible pour des raisons fonctionnelles. Cette troisième édition annule et remplace la deuxième édition parue en 2017. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) alignement sur l’édition la plus récente de l'ISO 22479 concernant le traitement en atmosphère sulfureuse humide; b) ajout d’une nouvelle Annexe D normative concernant l’applicabilité des essais antérieurs.
Elementi za zaščito pred strelo (LPSC) - 3. del: Zahteve za izolacijska iskrišča (IEC 62561-3:2023)
Ta del standarda IEC 62561 določa zahteve in preskuse za izolacijska iskrišča (ISG) sistemov za zaščito pred strelo.
Izolacijska iskrišča se lahko uporabljajo za posredno povezovanje sistema za zaščito pred strelo na druge bližnje kovinske konstrukcije, pri katerih neposredna povezava ni dovoljena zaradi funkcionalnih razlogov.
Običajna uporaba vključuje povezavo z naslednjimi sistemi:
• ozemljitveni sistemi električnih inštalacij,
• ozemljitveni sistemi telekomunikacijskih sistemov,
• pomožna ozemljila zemljekostičnih odklopnikov pod napetostjo,
• železniška ozemljila izmeničnih in enosmernih železnic,
• merilna ozemljila za laboratorije,
• inštalacije s sistemi katodne zaščite in blodečih tokov,
• servisni vhodni stebri za nizkonapetostne nadzemne kable,
• obvodne izolirane prirobnice in izolirani spojniki cevovodov.
Načini uporabe, pri katerih nastajajo sledilni tokovi, niso vključeni.
Pri števcih udarov strele za uporabo v nevarnih atmosferah morda veljajo dodatne zahteve za komponente.
OPOMBA 1: V državah članicah CENELEC so zahteve za preskušanje komponent za eksplozivne atmosfere določene v dokumentu CLC/TS 50703-2.
OPOMBA 2: Preskušanje komponent za eksplozivno atmosfero (kot je določeno v skupini standardov IEC 60079-10) v tem dokumentu ni zajeto.
