Annotation of standard text IEC 60034-30-3-ed.1.0 :
IEC 60034-30-3:2024 specifies efficiency classes for fixed-speed three-phase high-voltage cage induction motors in accordance with IEC 60034-1 that - have a rated voltage exceeding 1 000 V, but not exceeding 11 kV; - have a rated power from 200 kW to 2 000 kW; This document provides the global harmonization of energy-efficiency classes of three-phase cage induction motors with rated voltage above 1 000 V that are rated for direct online starting and fixed-speed operation at a 50 Hz or 60 Hz supply with sinusoidal voltage. IEC 60034-30-3:2024 specifie les classes de rendement pour les moteurs triphases a induction a cage a haute tension et a vitesse fixe conformement a lIEC 60034-1, qui - ont une tension assignee superieure a 1 000 V, mais qui ne depasse pas 11 kV; - ont une puissance assignee comprise entre 200 kW et 2 000 kW; Le present document prevoit lharmonisation globale des classes de rendement energetique des moteurs triphases a induction a cage dont la tension assignee est superieure a 1 000 V, qui sont assignes pour demarrer directement sur reseau et fonctionner a vitesse fixe sur une alimentation de 50 Hz ou 60 Hz avec une tension sinusoidale.
