0535: PEV Deployment: Policy Paper from Utility Perspective

The introduction of a large number of PEV loads to the Canadian electricity grid could lead to a number of technical bottlenecks ranging from localized to utility-scale effects. Many policymakers and stakeholders in the utility industry are seeking to understand these potential effects and to assess the risks associated with them before a large-scale roll-out of PEVs occurs in their regions. Although the physical effects of PEVs on the electricity grid are important to examine in detail, appropr

3043: Review and Summary of Key Standards and Guides for Station-Class Power Transformers

This project was developed to help utility engineers quickly identify and review the key standards and guides applicable to specific topics being faced by utility staff. Key standards and guides related to station liquid-filled power transformers have been identified and summarized. Key topics and sub-topics relevant to power transformers have been developed and related to each of the summarized standards (using a relevance matrix). A comparison of North American and worldwide standards has been

5092: Satellite Technology Applications for Monitoring Electric Utility T&D Assets and Rights-of-Way

A review of the potential applications of Earth observation satellites was carried out for the benefit of the electric utility industry to determine the feasibility of using the technology in its operations. Focusing on nine specific activities that usually make use of aerial photography and other forms of detailed geospatial data/information, the study provides examples of potential applications and assesses their likelihood of implementation and the forecasted barriers to their introduction.

0537: Emerging Energy Technologies: Technical and Economic Assessment

A technical and market assessment of fifteen different emerging technologies that are relevant to utility-scale electric power generation was undertaken to help the sponsors of the report keep abreast of the latest advances. The report was based on publically available data, in-house knowledge and expertise and, when required, targeted interviews with stakeholders. While the overall emphasis of the study was the North American market, when relevant, global developments were also discussed. The t

5079: Arc Flash on a Utility System

An arc flash on a transmission or distribution system results in high energy emission, mostly in the form of heat energy. This may present a concern to the safety of employees in the vicinity of the arc flash in open areas such as overhead lines, electrical distribution equipment, panels or substation equipment. A thorough understanding of arc flashes is necessary to accurately model them for identifying potential electrically hazardous areas, developing safe approach distances, and selecting th

0354: Mechanical Overhaul Guide for Hydroelectric Turbine Generators

This “Overhaul Guide” or “Refurbishment Guide” is concerned with the mechanical refurbishment of hydroelectric turbine generators, which typically operate for a period of 20 to 35 or more years before needing major intervention to restore their condition and prepare them for an extension of their service lives. Primarily, the document addresses vertical shaft units of the Francis and propeller/Kaplan types, although a section is devoted to horizontal shaft units and topic

33111: Guidelines for Assessment of Existing Foundations

The primary goal of this research effort is to establish best practice guidelines for the assessment, cost-effective maintenance and rehabilitation of existing transmission line (TL) foundation assets to meet future demands. Integrity of the structure-foundation system is often compromised due to aging, corrosion, erosion, cracking, challenging site characteristics, and extreme environmental or climatic conditions that can reduce useful service life. Assessing the exact mechanism and rate of fou
