Machines électriques tournantes - Partie 27: Mesures à l'arrêt des décharges partielles effectuées sur le système d'isolation des enroulements statoriques des machines électriques tournantes
Présente des modalités communes concernant les techniques de mesure et les appareils de mesure, la mise en place des circuits d'essai, les procédures de normalisation et les modes opératoires d'essai, la réduction du bruit, la documentation des résultats des essais, l'interprétation des résultats des essais pour les besoins des mesures à l'arrêt des décharges partielles dans les systèmes d'isolation des enroulements statoriques des machines électriques tournantes.
Električni rotacijski stroji - 27. del: Meritve delne izpraznitve na izolaciji statorskih navitij neaktivnih električnih rotacijskih strojev (IEC/TS 60034-27:2006)
Ta del IEC 60034 zagotavlja splošno podlago za merilne tehnike in instrumente, postavitev preskusnih vezij, postopke za normalizacijo in preskušanje, zmanjševanje hrupa, dokumentiranje preskusnih rezultatov in razlago rezultatov preskusa glede na nesprotne meritve delne izpraznitve na izolaciji statorskih navitij neaktivnih električnih rotacijskih strojev, kadar so preskušani z izmenično napetostjo do 400 Hz. Ta standard velja za električne rotacijske stroje, ki imajo palice, ali za tuljave s predhodno oblikovanimi navitji s prevodnim premazom. Običajno velja za stroje z oceno napetosti 6 kV in višjo. Metode merjenja, opisane v tem dokumentu, lahko prav tako veljajo za stroje brez prevodnega premaza. Vendar se lahko rezultati razlikujejo in niso zajeti v tem standardu.
