Why attend (especially if you work with surge arresters & lightning performance)
Dedicated session on line surge arresters (LSA). Topics include optimizing application of surge arresters to reduce lightning disturbances on overhead lines and enhancing LSA reliability via system studies.
Lightning data → operational decisions. Case studies on lightning analysis for OHL operation and risk management in transmission networks.
EGLA implementation & validation. Utility experience on optimizing/validating EGLA placement —useful where shielding backflash and insulation coordination drive performance.
Regional LSA experience. Insights from Latin America on increasing reliability of transmission lines through LSAs—good benchmarking for utilities weighing LSA retrofit programs.
Measurement & monitoring. Advances in measuring lightning current in LSAs and online/offline techniques to detect faulty surge arresters.
Material/condition topics relevant to arrester health. Lab evaluation of polymeric surge arresters exposed to internal humidity; complementary to field monitoring programs.
Modeling foundations. Tutorials on simplified lightning and grounding models—useful to align transient studies with field performance.
Distribution line protection context. Technical session on the role/advantages of shield wires on overhead distribution lines—a key alternative or complement to LSA strategies.
