![]() ![]() ![]() This would imply apparent quality improvement on the transmission lines in group 2. However, the annual outage rate elasticity of transmission lines of group 2 turns to be 0.33 while that of group 1 is 0.64. Results indicate that in both cases there is a significant log linear relationship between the transmission line outage and the line length. The method suggested is applied to analyze two sets of the 345 KV transmission line outage data of the Commonwealth Edison Company: group 1 contains transmission lines that had been installed before January 1974 group 2 consists of the lines that have been installed since January 1974. In this paper, a random effects Poisson regression model is used to quantify the relationship between the outage rate to the transmission line length. On December 7 and 8, Oncor held a public meeting to discuss the proposed Ramhorn Hill-Dunham 345 KV Transmission Line. The Cross Texas Transmission (CTT) 345kV Transmission Line Project was completed by Great Southwestern Construction and is one of MYR Group’s largest projects to date. One of the potentially influential factors is the length of the transmission line. The purpose of the proposed project is to: (1) Address reliability issues on the regional bulk transmission system, (2) alleviate congestion that occurs in certain parts of the transmission system and remove constraints that limit the delivery of power, (3) expand the access of the transmission system to additional resources, (4) increase the tr. Finding the factors that are related to varying transmission outage rates has been one of the major concerns of the reliability practitioners in the electric power industry. ![]()
