Thanks, Jason, for your contribution. I'd love to do a story on your success using this tool or, in general, your work on siting and land use. ... View more

Thanks, Brian. This is a very important factor in the determination of the cost of a transmission line. Changes in direction require special structures that can significantly add to the cost of transmission lines.  ... View more

Hi Lydia, An insulation coordination analysis or study examines the impact of surges on electric lines. Surges are caused by lightning and switching. The study analyzes the dielectric strength of the insulation to withstand the surges.  The IEEE standard for Insulation Coordination is IEEE Std 1313.1-1996. The reason I asked is that the data required for such a study would be asset information that could be managed by a GIS. I have not seen examples of GIS used as part of an insulation coordination study. The study would example the BIL of the insulators/lightning protection,  and any outside impact on their effectiveness such as damage, salt contamination, age, and avian impacts. Included in this analysis is the grounding scheme and its effectiveness effectiveness. I have not seen any transmission company using GIS as part of an insulation coordination study.  ... View more

Hi Chris,  Thanks for replying. The painting refers to tower painting. We used to do this regularly and it had its problems - requiring special workers. Yup, it is listed twice - good catch. Also, Raptor Protection/ Bird Guarding should be added. You are correct, these are high-level workflows. I'd like to dig deeper into these. Hey folks, can you provide more detailed workflows particularly those that you perform in which you don't use GIS, but could.  ... View more
