The mechanical effects of short-circuit currents in open air substations. Part II. Companion brochure to No. 105

A technical base for the methods to be suggested in substation design against short circuit mechanical loading. To understand the technical background behind IEC methods,to think about system design taking into consideration SCC loads at early stage and not simply verify structures against SCC loads, to give them trend to decrease SCC loading for uprating, refurbishement as well as designing of new substations.To help equipment suppliers when providing new design not only for static loads but also for dynamic loads.
