Abstract
All substation structures should be designed to withstand applicable loads that consider dead loads, wind, ice, line tensions, earthquakes, short circuits, construction, maintenance, electrical equipment operating loads, and other specified or unusual service conditions. This chapter discusses guidelines for developing substation structure loading criteria. It presents recommended guidelines regarding the application of the structure-loading criteria presented in this manual of practice. The methods for estimating loads—especially those for weather-related events—are mostly based on statistical models. These models, although scientifically correct, have limitations on the precision of their predictions. To ensure structural reliability, load factors are introduced to compensate for this uncertainty. The load factors and load combinations are selected based on the unique characteristics of typical electrical substation structures. Serviceability is the limit state in which the function, maintainability, durability, and appearance of substation structures and electrical equipment are preserved under normal usage.
