This work examining under what conditions trees cause service interruptions led to more such research and more importantly, to a revolution in maintenance priorities and practices.Read more...
At BGE, changes in vegetation management practices were required to improve upon system reliability. Due to resource limitations, a systematic approach to vegetation management was implemented. Vegetation management activities were prioritized by voltage class and construction type. Concurrent with this process, actual impacts to service reliability from tree/wire contacts were investigated through controlled testing. With some modification, the testing validated the systematic management approach.
