About This Item
IEEE PC62.21-2003-Cor_1/D5, Mar 2008 is an IEEE draft corrigendum for guidance on applying surge voltage protective equipment to AC rotating machinery rated 1000 volts and greater. It matters because it corrects key reference material in the original draft, helping engineers use the updated Table 2 and Annex A.1 and A.2 when evaluating insulation coordination and surge protection in power, energy, and industrial applications.
About IEEE PC62.21-2003-Cor_1/D5, Mar 2008
This technical document supports the application of surge voltage protective equipment for large AC rotating machines, with emphasis on equipment rated at 1000 volts and above. IEEE PC62.21-2003-Cor_1/D5, Mar 2008 is specifically a corrigendum, so its role is to replace and clarify selected content rather than introduce a full new framework. It is relevant to engineers reviewing protection practices, installation guidance, and related design or test references for high-voltage rotating machinery.
Where is IEEE PC62.21-2003-Cor_1/D5, Mar 2008 used?
IEEE PC62.21-2003-Cor_1/D5, Mar 2008 is typically used where AC motors, generators, and similar rotating equipment operate in higher-voltage industrial power systems. It is useful in facilities that depend on surge protective equipment to reduce stress from switching events or transient overvoltages. The corrigendum is especially relevant during specification review, retrofit planning, and engineering checks for insulation protection on machines connected to plant distribution networks or other energy-intensive installations.
Importance in practice
In practice, the corrigendum helps maintain consistency in technical interpretation by updating the referenced table and annexes used for application guidance. That can support more reliable selection of surge protective equipment, better alignment between design intent and field installation, and clearer documentation for compliance or procurement. For teams working with high-voltage rotating machinery, IEEE PC62.21-2003-Cor_1/D5, Mar 2008 may reduce ambiguity when comparing protection options and reviewing machine insulation risk.
