The performance of transformers in the presence of oscillatory transients is addressed in this guide. Oscillatory transients are typically produced by the interaction of the switching device, transformer, load, and system. This guide describes operating conditions that may produce oscillatory switching transient voltages damaging to the transformer insulation system. It discusses the electrical characteristics of the source, switching device, transformer, load and the nature of their transient interaction. It discusses several mitigation methods. Two generic examples are included. This guide focuses on mechanical switching devices and does not address semiconductor switching devices.

IEEE Draft Guide to Describe the Occurrence and Mitigation of Switching Transients Induced by Transformers, Switching Device, and System Interaction

Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
