Dynamic Impact Test Line Update Video

EPRI’s Dynamic Impact Test Line in Lenox, MA is used to simulate broken wire events that may occur on a transmission system and quantify the loads experienced by structures. EPRI is conducting research looking at the effect of line parameters including span length, conductor type and tension, and insulator length on dynamic loads. This research will help transmission engineers effectively design structures to be resilient against broken wire events. This video reviews portions of the dynamic impact test line setup and presents a few clips from the broken wire tests.
