Power transformers - Part 10: Determination of sound levels

IEC 60076-10:2016 defines sound pressure and sound intensity measurement methods from which sound power levels of transformers, reactors and their associated cooling devices are determined. The methods are applicable to transformers, reactors and their cooling devices - either fitted to or separate from the transformer - as covered by the IEC 60076 and IEC 61378 series. This standard is primarily intended to apply to measurements made at the factory. Conditions on-site can be very different because of the proximity of objects, including other transformers. Nevertheless, this standard is applied to the extent possible for on site measurements. This edition includes the following significant technical changes with respect to the previous edition: - additional useful definitions introduced; - definition of distribution type transformers introduced for the purpose this standard; - new clause for sound level measurement specification introduced; - requirement for 1/3 octave band measurements introduced for transformers other than distribution type transformers; - standard measurement distance changed from 0,3 m to 1 m for transformers other than distribution type transformers; - height of measurement surface is now clearly defined to count from the reflecting plane; - measurement surface formula unified; - correction criteria for intensity method introduced; - rules for sound measurements on dry-type reactors introduced; - figures revised; - new informative test report templates introduced (Annex B); - IEC 60076-10-1 (application guide) revised in parallel providing worthwhile information for the use of this standard.

Leistungstransformatoren - Teil 10: Bestimmung der Geräuschpegel

Transformateurs de puissance - Partie 10: Détermination des niveaux de bruit

L'IEC 60076-10:2016 définit les méthodes de mesure de la pression acoustique et de l'intensité acoustique par lesquelles sont déterminés les niveaux de puissance acoustique des transformateurs, des bobines d'inductance et de leurs dispositifs de refroidissement associés. Les méthodes sont applicables aux transformateurs, aux bobines d'inductance et à leurs dispositifs de refroidissement - qu'ils soient installés sur le transformateur ou en soient séparés - comme décrit dans les séries IEC 60076 et IEC 61378. La présente norme est principalement destinée aux mesures effectuées en usine. Les conditions sur le site peuvent être très différentes, à cause de la proximité d'autres objets, en particulier d'autres transformateurs. Néanmoins, la présente norme est appliquée dans la mesure du possible aux mesures sur le site. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - introduction de définitions utiles supplémentaires; - introduction d'une définition des transformateurs de distribution pour les besoins de la présente norme; - introduction d'un nouvel article relatif à la spécification des mesures du niveau de bruit; - introduction d'une exigence relative aux mesures de la bande de 1/3 d'octave concernant les transformateurs autres que les transformateurs de distribution; - modification de la distance de mesure normalisée qui passe de 0,3 m à 1 m pour les transformateurs autres que les transformateurs de distribution; - la hauteur de la surface de mesure est désormais clairement définie à partir du plan réfléchissant; - unification de la formule relative à la surface de mesure; - introduction de critères de correction concernant la méthode d'intensité; - introduction de règles relatives aux mesures du son sur des bobines d'inductance de type sec; - révision des figures; - introduction de nouveaux modèles de rapport d'essai informatifs (Annexe B); - révision de l'IEC 60076-10-1 (guide d'application) en parallèle et ajout d'informations utiles relatives à l'utilisation de la présente norme.

Močnostni transformatorji - 10. del: Opredelitev zvočnih jakosti

Ta del standarda IEC 60076 določa metode merjenja zvočnega tlaka in jakosti, na podlagi katerih se določijo ravni zvočne moči transformatorjev, reaktorjev in njihovih hladilnih naprav.
OPOMBA: za namene tega standarda izraz »transformator« pogosto pomeni »transformator ali reaktor«.
Metode se uporabljajo za transformatorje, reaktorje in njihove hladilne naprave (vgrajene v transformator ali ločene), kot določata skupini standardov IEC 60076 in IEC 61378.
Ta standard je namenjen zlasti uporabi za merjenja v tovarni. Pogoji na mestu uporabe se lahko zelo razlikujejo zaradi bližine objektov, vključno z drugimi transformatorji. Kljub temu se standard v največji možni meri uporablja za merjenja na mestu uporabe.
