Annotation of standard text IEC 60060-1-ed.4.0 :
IEC 60060-1:2025 is applicable to: - dielectric tests with direct voltage; - dielectric tests with alternating voltage; - dielectric tests with impulse voltage; - dielectric tests with combinations of the above. This document is applicable to tests on equipment having its highest voltage for equipment Um above 1,0 kV AC and 1,5 kV DC. This fourth edition cancels and replaces the third edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - The general layout and text have been updated and improved to make the standard easier to use, particularly the clauses for combined and composite test voltages. - The positive tolerance of the front time of lightning impulse voltage has been extended for Um > 800 kV to 100 % (= 2,4 µs). - For switching impulse voltage, a front time has been introduced, similar to lightning impulse voltage and with the new front time the standard switching impulse is defined as 170/2 500 µs. - The requirements for precipitations have been adjusted depending on Um. - A new Annex C, "Procedure for manual calculation from graphical waveforms" has been incorporated. - No examples of software have been given in Annex D, "Guidance for implementing software for evaluation of lightning impulse voltage parameters". - The annex relating to the "Background to the introduction of the test voltage factor for evaluation of impulses with overshoot" has been deleted. - A new informative Annex F, "New definition of the front time of switching impulse voltage" has been incorporated. NOTE 1 Alternative test procedures can be required to obtain reproducible and significant results. The choice of a suitable test procedure is considered by the relevant Technical Committee. NOTE 2 For voltages Um above 800 kV it is possible that some specified procedures, tolerances and uncertainties will not be achievable. LIEC 60060-1:2025 sapplique aux: - essais dielectriques sous une tension continue; - essais dielectriques sous une tension alternative; - essais dielectriques sous une tension de choc; - essais dielectriques qui combinent les essais ci-dessus. Le present document sapplique aux essais de materiels dont la tension Um du materiel la plus elevee est superieure a 1,0 kV en tension alternative et a 1,5 kV en tension continue. Cette quatrieme edition annule et remplace la troisieme edition parue en 2010. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - La presentation generale et le texte ont ete mis a jour et ameliores pour faciliter lutilisation de la norme, en particulier les articles et paragraphes relatifs aux tensions dessai combinees et composites; - La tolerance positive sur la duree du front des tensions de choc de foudre a ete portee a 100 % (= 2,4 µs) pour Um > 800 kV. - Pour les tensions de choc de manouvre, une duree du front a ete adoptee de maniere analogue aux tensions de choc de foudre; avec la nouvelle duree du front, la tension de choc de manouvre normalisee est fixee a 170/2 500 µs. - Les exigences daspersion dans les essais sous pluie ont ete adaptees en fonction de Um. - Une nouvelle Annexe C, "Procedure de calcul manuel a partir de formes dondes graphiques" a ete ajoutee. - Les exemples d’ensembles logiciels ont ete enleves de lAnnexe D, "Recommandations pour la mise en ouvre dun logiciel devaluation des parametres des tensions de choc de foudre". - Lannexe intitulee "Arriere-plan de lintroduction du facteur de tension dessai pour levaluation des chocs avec depassement" a ete supprimee. - Une nouvelle Annexe F informative, "Nouvelle definition de la duree du front des tensions de choc de manouvre" a ete ajoutee. NOTE 1 Des variantes aux procedures dessai peuvent etre exigees pour obtenir des resultats reproductibles et pertinents. Il convient que le Comite detudes competent choisisse la procedure dessai appropriee. NOTE 2 Pour les tensions Um superieures a 800 kV, il est possible que certaines des procedures, tolerances et incertitudes specifiees ne soient pas realisables.
