IEEE PC57.19.100/D10, July 2012 is a draft technical document for the application of power apparatus bushings in power, energy, and industrial systems. It is intended to help define how bushings are selected, applied, and evaluated so equipment can operate with appropriate insulation, reliability, and electrical performance. For engineers and buyers working with transformer and other power apparatus designs, this standard provides a focused reference for consistent application decisions and practical compliance review.

IEEE PC57.19.100/D10, July 2012 overview

This draft guide addresses the engineering context around power apparatus bushings, which are critical components where conductors pass through grounded barriers or enclosures. IEEE PC57.19.100/D10, July 2012 is relevant to application planning, helping users consider ratings, insulation coordination, and operating conditions when specifying bushing equipment. As a draft guide, it is particularly useful for understanding recommended application practices and the technical factors that affect safe and dependable service in electrical power apparatus.

Typical use cases

This standard is typically used when specifying or reviewing bushings for transformers, reactors, and related high-voltage apparatus in utility and industrial power systems. It can support engineering teams during design selection, procurement review, and application checks where insulation performance and electrical stress must be matched to the installation. IEEE PC57.19.100/D10, July 2012 is also useful when comparing bushing options for maintenance planning, retrofit work, or equipment documentation tied to power system assets.

Why this standard matters

Power apparatus bushings are small components with a major impact on system reliability, and this guide helps reduce uncertainty in how they are applied. IEEE PC57.19.100/D10, July 2012 supports more consistent design control, which can improve safety margins, reduce insulation-related risk, and make technical procurement clearer. For organizations managing specification and testing decisions, the document helps align expectations for performance and application practice across power equipment projects.
