G595: Experience In Pulveriser Coal Fires and Explosions Outside USA

In the early 1980's there were indications that not only were p.c. mill fires and explosions a major cause of electric utility down time, but that foreign experience with p.c. mill study was established to survey foreign utility experience with pulverized coal (p.c.) fires and explosions and to relate this to U.S. experience. Sources of foreign p.c. technology were located and visits made to Japan, Australia, England, France, Germany and Switzerland to gather foreign knowledge and experience wit

4105: An Analysis of PhoDAR vs. LiDAR for Collecting Spatial Data by Electrical Utilities and Operational Recommendations for Use

Advancements and innovations in mapping technologies provide electrical utility operators with timely and multidimensional spatial data to meet compliance requirements, situational awareness, and predictive modeling in support of vegetation management and asset monitoring. Photogrammetry techniques commonly referred to as PhoDAR or Structure from Motion (SfM), and LiDAR are common 3D digital mapping techniques that are continually advancing and thus gaining popularity for use in the market.

5049: Assessment Criteria Used to Repair, Refurbish, or Replace Underground Cables

The underground cable system is often the most expensive part of a utility's assets to replace. It involves considerable construction and restoration expenses. Faced with aging equipment that's causing problems, many utilities have difficulty deciding what to repair and what to replace. They lack the means to analyse their underground systems and make the best choices on how to improve them. This report examines methods of collecting and manipulating information on both the installed system and

3719: Precision Assessment of Power Line Response to Lightning

There is a significant opportunity to better understand and improve the performance of transmission and distribution systems in response to direct and indirect lightning strikes using equipment and data currently available to the industry. To date, the operational analysis of lightning’s impact on power systems (lines) has been limited to information about basic lightning correlations and statistics, which are generally limited to the occurrence of electrical faults within the power system

33120: Galloping Mitigation – Performance Evaluation of Various Anti-Galloping Control Devices

Galloping is an extremely destructive type of wind-induced conductor motion. For overhead lines, typical galloping mitigation techniques include the use of various in-span mechanical anti-galloping devices that utilize different mechanisms to mitigate galloping motion or reduce some impacts on the line caused by galloping. Field experiences have indicated that the performance of different anti-galloping devices varies significantly. To obtain better confidence regarding the performance of these
