IEEE 117-2015

117-2015 is a technical standard for wound AC electric machinery, addressing the engineering and performance considerations that matter in rotating electrical equipment. It is relevant to materials, insulation behavior, and machine design where alternating current machines must operate reliably under defined conditions. For users working with power, energy, and industrial applications, this standard helps support consistent specifications and more controlled technical decision-making around machine construction and evaluation.

About 117-2015

117-2015 focuses on wound AC electric machinery, a category that typically includes machines with windings designed for alternating-current operation. The standard is useful where design choices, electrical characteristics, and material performance need to be described in a stable technical format. In this context, the document helps define expectations for engineering use, especially where dielectrics, insulation systems, and machine behavior are part of the specification or review process. It is a practical reference for structured technical communication.

Where is 117-2015 used?

This standard is commonly used in settings involving the design, procurement, and evaluation of wound AC electric machinery for power and industrial systems. It may apply to equipment used in generation, conversion, or plant operations where electrical machines must meet defined technical requirements. Engineers, specifiers, and testing teams can use 117-2015 when comparing machine designs, reviewing insulation-related details, or aligning documentation for equipment intended for reliable AC operation.

Importance in practice

In practice, 117-2015 supports clearer expectations for wound AC electric machinery, which can reduce ambiguity during design review, sourcing, and inspection. A consistent standard helps teams compare products on the same technical basis and may improve coordination between engineering, manufacturing, and quality functions. For electrically stressed equipment, careful attention to materials and insulation-related requirements is important for performance and risk reduction. Using 117-2015 can help reinforce compliance and more predictable machine selection.
