About IEEE PC57.19.100/D10, Jul 2025

This draft guide addresses the practical use of power apparatus bushings, which are commonly used to carry conductors through grounded barriers in high-voltage equipment. IEEE PC57.19.100/D10, Jul 2025 is relevant to application decisions where insulation performance, electrical clearances, mechanical arrangement, and operating conditions must be considered together. As a draft guide, it is intended to support technical review, design planning, and specification work for bushings used in power apparatus and related engineering environments.

Where is IEEE PC57.19.100/D10, Jul 2025 used?

IEEE PC57.19.100/D10, Jul 2025 is typically used in the planning and application of bushings for equipment such as transformers, switchgear assemblies, and other power apparatus that rely on a controlled passage through an enclosure or grounded structure. It is most relevant in utility, substation, and industrial power systems where insulation coordination and equipment interface details matter. The guide can also support procurement and engineering review when bushing selection must match voltage, environment, and installation requirements.

Importance in practice

In practice, IEEE PC57.19.100/D10, Jul 2025 helps reduce ambiguity when specifying and applying bushings for critical electrical equipment. Clear application guidance can improve consistency across design, testing, and procurement activities while lowering the risk of mismatch between the bushing and the apparatus it serves. For organizations working with power systems, the standard can support safer installations, more reliable performance, and better control of insulation-related concerns in demanding operating conditions.
