REASONS FOR FAILURE OF TRANSMISSION LINES AND THEIR PREVENTION STRATEGIES

Abstract
Transmission line towers, though designed per code provisions, may fail during mandatory testing required in many countries, which leads massive damage to power system. Different types of premature failures that are observed during various full-scale testing of transmission line towers and their results are discussed in detail. Importance of design assumptions and connection detailing in overall performance of towers were studied. Importance of secondary member design and connection detail in overall performance of the tower was studied. Non-linear finite element analysis is useful in understanding the system behavior and for prediction of failure pattern and ultimate load. Based on the test results the importance of studying the failures is highlighted. The need for implementing various failure prevention strategies in transmission line towers has also been emphasized lucidly.
