Recommended practices for the engineering and design of flexible and rigid bus connections for bus and equipment in electric power substations located in seismically active areas are provided in this document.

This document provides recommended practices for the engineering and design of flexible and rigid bus connections for bus and equipment in electric power substations located in seismically active areas. It covers the design of buswork connections in the seismic qualification of equipment covered within the scope of IEEE Std 693™.

This document provides recommended practices to give guidance to the substation engineer regarding seismic considerations in the engineering and design of buswork, and to provide engineers and equipment manufacturers with the knowledge of the dynamic effects of connections on interconnected equipment during seismic events.
