Electrical Connectors for Overhead Lines
Electricity Today September 2015
Utility distribution systems utilize a variety of connectors to join and attach overhead conductors. These components are simple and relatively inexpensive; however, due to their critical function and the large number of components utilized in the electrical system, they deserve some consideration from the maintenance perspective.
Torrefaction Technologies Canadian Biomass July 2011
A look at how torrefaction works, its demand, and projects in development across Canada and Europe. The Montreal-based Centre for Energy Advancement through Technological Innovation, or CEATI International Inc., is currently coordinating the evaluation of torrefaction and other technologies on behalf of several major utilities from Canada, the United States, and Europe, as well as Canadian government agencies.
Lest we forget: Learning from International Dam Incidents Water Power and Dam Construction October 2010
The combination of ageing dams, retirement of experienced dam engineers and increased consequences of dam failure due to downstream development underscore the need to better ensure the future safety of dams worldwide. Past experience must not be forgotten and lessons learned must be captured for future generations. The Centre for Energy Advancement through Technological Innovation (CEATI International) is paving the way forward in global communication, coordination and collaboration through their Dam Safety Interest Group (DSIG). A selection of case studies from the organisation’s recent workshop on international dam incidents and failures is presented below.
Dam Safety: Room for Improvement HydroReview September 2010
While dams provide tremendous benefits ranging from flood control to power generation, they also represent a risk to public safety. Some of North America’s leading dam safety experts sat down with Hydro Review to discuss efforts to improve dam safety.The participants were: Brian Becker, chief of the Bureau of Reclamation’s Dam Safety Program; Charles Pearre, dam safety program manager, U.S. Army Corps of Engineers; Dan Mahoney, director of the Federal Energy Regulatory Commission’s Division of Dam Safety and Inspections; Constantine “Gus” Tjoumas, technology coordinator for Dam Safety, CEATI International; Paul C. Rizzo, president of Paul C. Rizzo Associates Inc.; and Warren Witt, manager of hydro operations, AmerenUE.
Dam Safety: Review of Geophysical Methods to Detect Seepage and Internal Erosion in Embankment Dams Hydro Review March 2010
Internal erosion is the second largest cause of failure of earthfill dams worldwide. Damages resulting from internal erosion can lead to expensive remediation. Typical dam safety surveillance consists of visual inspections supported by limited instrumentation. However, internal erosion can become quite advanced before the problem is detected via these means. Recently, interest has grown regarding the use of non-intrusive geophysical techniques to facilitate early detection of anomalous seepage, piping, and internal erosion.
These needs prompted the launch of a collaborative research project under the auspices of CEATI’s Dam Safety Interest Group (DSIG) to study the current state-of-practice regarding geophysical methods applied to embankment dams.
