SWITCHING IT UP: A NEW INNOVATIVE 3-WAY GOAB SWITCHING STRUCTURE

This month’s Featured Technical Paper is from the Proceedings of the 2025 International Conference of Doble Clients. The paper is titled: Switching It Up: A New Innovative 3-Way Goab Switching Structure.

Abstract

The Lower Colorado River Authority (LCRA) faced significant challenges with the traditional 3-way GOAB (gang operated air-break) transmission line switches, which led to operational and safety issues due to their tendency to bind, seize, and break. In response to these challenges, LCRA has pioneered a new innovative 3-way GOAB alternative design that addresses these issues by enhancing flexibility in operation, safety by design, and overall reliability. Launched in 2024, the first installation of this innovative two-monopole switching structure design not only meets all operational and maintenance requirements but also comes at a significantly lower cost, footprint, and shorter construction timeline compared with another 3-way box structure alternative. This advancement represents a significant step forward in LCRA's commitment to improving infrastructure and service reliability through design solutions.
