Overview

The IEC 60050-151:2001/AMD1:2013 is an important amendment to the International Electrotechnical Vocabulary (IEV), Part 151, which focuses on electrical and magnetic devices. Issued by the International Electrotechnical Commission (IEC), this amendment updates terminology and definitions critical for professionals working with electrical and magnetic equipment. The IEV provides standardized language that enhances clarity and consistency across international electrotechnical standards, facilitating effective communication and compliance worldwide.

This amendment specifically revises terms related to electrical and magnetic devices such as windings, quality factor (Q factor), dissipation factor, and loss angle. By defining these key concepts precisely, IEC 60050-151 supports engineers, designers, and manufacturers in understanding device behavior and ensuring standardized specifications in electrical engineering projects.

Key Topics

  • Winding (Enroulement): Defined as an assembly of interconnected turns or coils that operate together. Windings are essential components in electrical machines and transformers used to generate magnetic fields or produce voltages when interacting with magnetic fields. The amendment clarifies that the number of turns (N) can be non-integer, addressing practical design variations.

  • Quality Factor (Q Factor): Updated definitions differentiate the Q factor for:

    • Linear non-radiating two-terminal elements or circuits, where it is the ratio of reactive power to active power, characterizing energy loss within capacitors or inductors.
    • Resonant circuits, where it represents the sharpness of the resonance, calculated as the ratio of energy stored to energy dissipated over a cycle.
  • Dissipation Factor (Loss Factor): Defined as the reciprocal of the quality factor (d = 1/Q), it quantifies the energy loss in electrical components or resonant circuits. This is critical in assessing the efficiency of devices such as capacitors and inductors.

  • Loss Angle (Angle de Perte): The angle where the tangent equals the dissipation factor, illustrating the phase difference associated with energy dissipation in two-terminal elements or circuits. The amendment clarifies its usage and references related electromagnetic definitions.

These precise definitions align with practical electrical engineering concepts, ensuring uniform use across technical documentation.

Applications

  • Electrical Equipment Design: The standardized terminology aids engineers designing coils, transformers, inductors, and capacitors by providing clear descriptions of performance factors like quality factor and loss angle.

  • Industry Compliance: Manufacturers referencing IEC terminology can ensure their products meet international standards, improving compatibility and safety.

  • Fault Analysis and Diagnostics: Understanding dissipation and loss factors helps practitioners assess component health, energy efficiency, and potential degradation.

  • Education and Training: Academic courses and training programs benefit from the harmonized vocabulary, facilitating consistent learning and knowledge sharing worldwide.

Related Standards

  • IEC 60227: Pertains to polyvinyl chloride insulated cables, referenced in the amendment for compliance requirements related to electrical devices.

  • IEC 60050 (General IEC Electrotechnical Vocabulary): This amendment is part of the broader IEC 60050 series, which standardizes electrotechnical vocabulary across numerous subfields.

  • Electropedia (www.electropedia.org): The IEC online dictionary providing access to over 30,000 electrotechnical terms, including those in IEC 60050-151.

  • Other IEC Standards on Electrical Machines and Components: Related standards detail specifications and testing methods for devices utilizing windings and featuring Q factor and dissipation characteristics.
