Improving Transmission Line Design by Using Reliability Techniques

This paper discusses present design methods of transmission lines and shows how they can be improved by using reliability and statistical techniques. Methods of calculating line reliability are discussed with special emphasis on the most important parameters. This paper also deals with possible formats for a new design standard based on reliability techniques with a comparison of IEC/TC11 proposed format and the load and resistance factor (LRFD) proposed in EPRI research project 1352.
