P693a - Recommended Practice for Seismic Design of Substations Amendment: Alterations of Transformers, Transformer Bushings and Time Histories
The recommended practice amendment alters recommendations for transformers, transformer bushings, and time histories. The amendment alters recommendations for the seismic design and qualification of transformers and transformer bushings. The amendment alters recommendations for the input motion time histories used for testing and analysis.
Seismic design recommendations for substations, including qualification of different equipment types are discussed. Design recommendations consist of seismic criteria, qualification methods and levels, structural capacities, performance requirements for equipment operation, installation methods, and documentation.
