(Main)High-voltage test techniques - Part 1: General definitions and test requirements
High-voltage test techniques - Part 1: General definitions and test requirements
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.
Hochspannungs-Prüftechnik - Teil 1: Allgemeine Begriffe und Prüfbedingungen
Technique des essais à haute tension - Partie 1: Définitions et exigences générales
L'IEC 60060-1:2025 s'applique aux:
- essais diélectriques sous une tension continue;
- essais diélectriques sous une tension alternative;
- essais diélectriques sous une tension de choc;
- essais diélectriques qui combinent les essais ci-dessus.
Le présent document s'applique aux essais de matériels dont la tension Um du matériel la plus élevée est supérieure à 1,0 kV en tension alternative et à 1,5 kV en tension continue.
Cette quatrième édition annule et remplace la troisième édition parue en 2010. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- La présentation générale et le texte ont été mis à jour et améliorés pour faciliter l'utilisation de la norme, en particulier les articles et paragraphes relatifs aux tensions d'essai combinées et composites;
- La tolérance positive sur la durée du front des tensions de choc de foudre a été portée à 100 % (= 2,4 µs) pour Um > 800 kV.
- Pour les tensions de choc de manœuvre, une durée du front a été adoptée de manière analogue aux tensions de choc de foudre; avec la nouvelle durée du front, la tension de choc de manœuvre normalisée est fixée à 170/2 500 µs.
- Les exigences d'aspersion dans les essais sous pluie ont été adaptées en fonction de Um.
- Une nouvelle Annexe C, "Procédure de calcul manuel à partir de formes d'ondes graphiques" a été ajoutée.
- Les exemples d’ensembles logiciels ont été enlevés de l'Annexe D, "Recommandations pour la mise en œuvre d'un logiciel d'évaluation des paramètres des tensions de choc de foudre".
- L'annexe intitulée "Arrière-plan de l'introduction du facteur de tension d'essai pour l'évaluation des chocs avec dépassement" a été supprimée.
- Une nouvelle Annexe F informative, "Nouvelle définition de la durée du front des tensions de choc de manœuvre" a été ajoutée.
NOTE 1 Des variantes aux procédures d'essai peuvent être exigées pour obtenir des résultats reproductibles et pertinents. Il convient que le Comité d'études compétent choisisse la procédure d'essai appropriée.
NOTE 2 Pour les tensions Um supérieures à 800 kV, il est possible que certaines des procédures, tolérances et incertitudes spécifiées ne soient pas réalisables.
