Annotation of standard text IEC 60034-28-ed.2.0 :
IEC 60034-28:2012 applies to three-phase low-voltage cage induction motors of frame numbers 56 to 400 as specified in IEC 60072-1. This standard establishes procedures to obtain values for elements of single phase equivalent circuit diagrams from tests and defines standard elements of these diagrams. This edition includes the following significant technical changes with respect to the previous edition: - the formulae are now all given for equivalent star-connection equivalent circuit diagrams; - procedures for the determination of equivalent circuit parameters from a load curve test as an alternative to the reverse rotation and locked rotor tests have been added. La CEI 60034-28:2012 sapplique aux moteurs a induction a cage basse tension triphases de designations de carcasses entre 56 et 400, specifies dans la CEI 60072-1. La presente norme definit des elements normalises de schemas de circuits equivalents monophases et etablit a partir dessais des procedures pour obtenir des valeurs pour ces elements. Cette edition inclut les modifications techniques significatives suivantes par rapport a ledition precedente: - toutes les formules sont maintenant donnees pour des circuits de connexion en etoile equivalente; - les procedures pour la determination des parametres du circuit equivalent a partir dun test de courbe de charge, comme alternative aux tests en rotation en sens inverse et rotor bloque rotors, ont ete ajoutees.
