Effect of Processes of Component Entry in Reliability of Electrical Distribution Networks

Information about network components is of great importance for asset management decision making. This information is needed as input for the asset management decision process to come to a decision. To be able to extract the requested information، analysis and evaluation are needed. On the other hand، for efficient and economical asset management from reliability view point، analysis of failure rate for determination of origin of fault in component is an important task for asset manager. The failure rate of components is obtained by gathering data in outage management process that is available usually in detail in outage databases in electrical distribution. In this paper، failure analysis of process is obtained by assessment of process of component entry in distribution system. In this analysis، failure factors and sub-factors of each process is assigned by focus group and then relation between factors and causes of component failure is obtained by Delphi method. Finally، reasons of process-based failure are invested by modeling of failure rate for each process.
