Abstract
Transmission line towers forms an integral part in the transmission of electric power. Even though the transmission line towers are designed properly as per various codalprovision specified by various countries, they may collapse during even on moderate circumstances if they are poorly designed. Studies were made on various types of Failure cases, that were observed on the full-scale prototype testing of a transmission tower at Tower Testing and Research Station, Structural Engineering Research Centre (CSIR – SERC), Chennai, Tamilnadu, India. This paper summarizes the Full scale testing of a 400 kV DC Transmission line tower, which was abruptly failed under safer load itself. The sudden failure of the Leg member in the +0M body extension on the compression region causes sudden failure of the tested tower.
