Response Spectrum for Short Circuit Loads on Rigid Bus
Publication: Electrical Transmission and Substation Structures 2022: Innovating for Critical Global Infrastructure
ABSTRACT
The current industry design standard for short circuit forces in substations prescribes a static analysis considering peak instantaneous force. Various complex dynamic analyses and full-scale tests have demonstrated that this approach is highly conservative. The response spectrum for short circuit loads was developed to account for dynamic effects and reduce design forces for aluminum bus, insulators, supports, and foundations. It is significantly simpler and less labor intensive than the rigorous dynamic analysis option described in IEEE 605-2008. The approach also produces results that correlate extremely well with rigorous dynamic analysis.
