Advancements in Braced Line Post Testing by Jeff Butler

The advantages of braced line post assemblies has led to a rise in their use as an option in transmission line design and these assemblies are also seeing application at increasingly higher voltages and mechanical ratings. However, the standards do not well define proper testing techniques to determine the electrical and mechanical ratings for these assemblies. Yet the complexity of these assemblies, as a combination of a post insulator and a braced suspension insulator, results in challenges to properly test and rate them according to current procedures. This presentation will outline efforts toward acceptable standardization of the important aspects of these assemblies and propose advancements in test procedures and rating methods.
