IEEE PC57.19.100/D9, Sept 2011 is a draft technical document for the application of power apparatus bushings, offering guidance for engineers working with insulated connections in power and energy equipment. It is relevant where bushing selection, installation, and performance need to be considered in relation to electrical and mechanical service conditions. For organizations handling high-voltage apparatus, this standard helps support more consistent design and evaluation decisions.

IEEE PC57.19.100/D9, Sept 2011 overview

This draft guide addresses how power apparatus bushings are applied within electrical systems and equipment, with attention to their role as components that carry conductors through grounded barriers. IEEE PC57.19.100/D9, Sept 2011 is useful in contexts where insulation coordination, operating conditions, and equipment interface requirements must be understood together. The document is most relevant to power engineering work involving specification, review, or assessment of bushing use in apparatus intended for reliable service.

Typical use cases

Typical use cases include planning and specifying bushings for transformers, reactors, switchgear, and other power apparatus where a conductor must pass through an enclosure or tank wall. IEEE PC57.19.100/D9, Sept 2011 may also support engineering reviews for insulation performance, installation practices, and compatibility with system voltage and loading conditions. It is especially relevant during equipment procurement, design verification, and field evaluation in utility and industrial power applications.

Why this standard matters

This standard matters because bushing selection and application can affect safety, reliability, and long-term equipment performance. Using IEEE PC57.19.100/D9, Sept 2011 can help reduce ambiguity in design and procurement decisions, especially where insulation levels, environmental exposure, and operating duty must be aligned. It also supports more consistent technical communication between manufacturers, engineers, and asset owners when reviewing power apparatus requirements and testing expectations.
