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

7054: Variable Speed Drive Calculator Tool Development

This manual describes how to use the CEATI Fan and Pump VSD Calculator (Calculator) to compute first-year annual electrical energy savings (kWh) for a fan or pump that has been, or will be, upgraded by the addition of a Variable Speed Drive (VSD).This manual explains the working of the accompanying Excel workbook. The workbook also includes manual contents as part of its "help" functionality.The Calculator is designed to be used in conjunction with on-site data collection. Included among the dat

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

0227: Dam Safety Inspection Procedures, Guidance and Training for Plant Operators

This Guide is intended to help hydroelectric plant operatorsrecognize, understand, and respond to potential dam safety hazards.Recognizing that no two hydroelectric projects are exactly alike and that the most effective dam safetysurveillance practices are those that are tailored to a specific site, this document has been designed so thatreaders can focus on content that is directly relevant to the types of structures they encounter and for which theyare responsible.This Guide is intended to ser

0308B: CPF: Self-Lubricating Materials for Hydraulic Turbines Experience Feedback

The objective of the study is to comment on the overall field performance of the self-lubricating materials in use in the hydraulic turbines, focusing on the turbine wicket gate bushings, operating linkage, servomotor bushings and operating ring wear pads.A database consisting of generating station general information, bushing characteristics, bushing dimensions and operational data, is therefore prepared to summarize the applications/installations of the self-lubricating bushings. The database,

5040: Non-Destructive Condition Assessment of ACSR Distribution Conductors

The rates of deterioration of specific distribution line components, such as conductors, are largely unknown and therefore as lines continue to age, their remaining physical life becomes of increasing concern, bringing to the forefront issues such as public and worker safety, competition, reliability, availability and system planning. Consequently, the desire to assess the actual condition of all line components is also increasing. Conductors are of primary interest because their condition often
