Mechanical Aging of Surge Arrester Leads
Non-Gapped Line Arresters (NGLA) are often applied to improve the lightning performance of transmission lines. While these transmission line surge arresters (TLSA) may perform well electrically, their installation is often compromised by failures of the connection leads or the disconnector. This content describes the accelerated testing results, highlighting issues that could be observed on the field.

Alternative Grounding Materials for Counterpoises
Rising construction costs and increasing theft have made it clear that alternative grounding materials are needed. Carbon steel or aluminum are potential alternative materials to copper for counterpoises. This content summarizes the field tests performed to verify the practicality of both materials for use as counterpoises and the potential necessity of cathodic protections.
