This paper summarizes engineering solutions. This would imply apparent quality improvement on the transmission lines in group 2. This involved bisecting an existing 345 kV transmission line and constructing a new 345 kV to 138 kV substation. 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. Electrical distribution and secondary transmission are usually done within the MV range of voltages. 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. This talk will focus on the electrical aspects of transmission lines. Transmission lines are a civil, mechanical and electrical engineering challenge. Electricity in the context that I’ll use it includes both power and energy. Their main purpose is to connect load to generation. In this paper, a random effects Poisson regression model is used to quantify the relationship between the outage rate to the transmission line length. Introduction Transmission lines are the highways for electricity. One of the potentially influential factors is the length of the transmission line. 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. The 345-kV Iatan-Nashua line runs 29.85 miles from Iatan Station near Weston, Missouri, to the Nashua station near.
