Removing these crashes makes it difficult and even impossible to use these lines. The purpose of the analysis is to identify vulnerabilities, find weak infrastructures or critical situations so that decision makers can take possible measures to reduce weaknesses and critical situations; accordingly, vulnerability measures should be developed to help decision makers. The overall vulnerability index is an essential factor in the comparison of the different types of network transmission vulnerabilities or adverse weather events. The more important thing is that the weak areas in the network should be identified in order to take measures to reduce the vulnerability. As a result, this model considers the vulnerability of location-time correlations of difficult climatic conditions and integrates existing concepts into a single framework. The main purpose of this paper is to discuss the vulnerability of power transmission lines to atmospheric hazards; current methods do not take into account spatial correlations - when weather conditions and electrical models of power systems are not considered. They either concentrate on simulating power systems regardless of difficult weather conditions, or focus on forecasted power line overheads without considering the consequences of power outages. Therefore, in this research, the core of the vulnerability assessment is done with the requirement analysis to adapt vulnerability indicators. Finally, measures can be taken to reduce vulnerability.
