Live working practices & development for EGAT overhead line in Thailand

Abstract

This paper describes the LW experienced on EGAT transmission line, the development and implementation of LW including training programs for the live line maintenance team through EGAT Lineman Training School. EGAT has extensive experience with LW using the Insulating tool and Bare-hand (contact) technique on conventional up-to 500 kV lines. EGAT also has the plan to develop LW technique suit to the constraints on the tower configuration and tower window clearances as well as the unseen problem on insulator string cause by bird drop as the previous serious experienced as well. Facing the new challenge, EGAT engineers carefully considered the suitable and sound methodology for the line maintenance by study about the innovative technique that success perform in many country to select the safe and more safe method that accept by the LW team. The lineman training school was set up for the actual training program for the new technique especially the LW training site for actual simulation in each safety scenario before the actual practical training program. The paper show the overall actual development in LW activity in Thailand such as type of LW, LW activity, live working in-house development and training program under EGAT lineman training school. Finally the summary overall actual LW activity and the future development plan of the new LW activity for EGAT in THAILAND shall be present as well.
