    Cap and Pin Type Bus Support

    The Utility Co I work for has not had good experience with silicone polymer insulators, especially in high contamination areas such as near the sea...we only get about 5-10 years out of them. They perform better in inland areas with low or moderate contamination. Have you considered porcelain...

    Transition from Detailed Engineering to Upstream Engineering

    Hi, I work in the Transmission Planning Dept of a large utility and two of my colleagues were previously employed in "detail engineering". They can both run load flow studies, transient stability studies, etc. as well as any of the other engineers. The transition may be a challenge but it's...

    Transmission impedence vs. rated MVA capability

    Greetings, I am working on verifing impedence data for a large number of transmission transformers. The data is being used in a GE PSLF powerflow model of a large transmission nework. I would like to develop quick way to flag any bad data. In the interest of time, I can't go pull the test...

    Geothermal? Better in some states?

    itsmoked, Currently some of the steam is recycled and reinjected, I think about 20%. Nature provides most of the recharge, however this takes time. Currently, output is pretty stable a 900 MW. I think I see addition wastewater reinjection projects in the future and expansion of production...

    Electric Car with a 10 minute recharge? Realistic?

    A company called ZAP! (www.zapworld.com) located in Santa Rosa, CA claims it is developing a electric SUV that can be recharged "in as little as 10 minutes". Somehow I find this a bit optimistic. This got me thinking, and I looked at the specs for an existing state-of-the-art Battery system...
