3503: Security System Design and Engineering Specification Templates for Electrical Utility Use

Security systems and devices are increasingly being used by electric utilities to protect their transmission assets. Utilities require a high degree of reliability, safety and functionality from their security equipment. They require design, procurement, commissioning, and operational specifications which address their security needs in electrical station applications. Security system integrators are often hired by utilities to recommend equipment and designs for electrical stations due to a lac

3201: Insulator Diagnostics

A study was undertaken to determine whether alternative remote diagnostic methods, for use froman aircraft or from a moving or stationary ground based vehicle, have been developed foreffectively measuring the integrity of AC and DC energized porcelain suspension insulator stringsoperating at 100 kV pp or greater. This investigation was sponsored by CEATI (CEATechnologies Inc.) and various utility participants of the TLAMIG (Transmission Lines AssetManagement Interest Group). A literature search

3326: Guide to Define Design Criteria for Outdoor Station Insulators Taking Into Account Pollution and Icing

The objective of this report is to realize a comprehensive literature survey related to insulator performance under ice and pollution conditions, especially in regards to station insulators. This will be used, along with contractor experience, to prepare a guide dealing with design criteria for outdoor station insulators under ice and pollution conditions. This report explains how to assess a location for the co-incidence of meteorological conditions (ice, snow or fog) and pre-existing conditi

3246: Increasing Capital Investments to Minimize Maintenance Costs

Transmission line asset managers are continually looking for more cost effective ways to minimize overall life cycle costs of transmission lines, usually by trading off Operating and Maintenance (O&M) and capital investments. The focus of this study is on investigating and identifying “increased capital” technologies, both traditional and new, that will lower the overall life cycle cost of transmission lines ownership. This is done by reducing O&M costs or, in some cases, extending t

3256: CPF: Guide for Cathodic Protection of Transmission Line Structures

The primary purpose of this document is to provide practical information and guidance on the design, operation and maintenance of cathodic protection systems ― galvanic systems in particular ― for transmission and distribution (T&D) structures.Electrical transmission structures are composed of two distinct sections: the aboveground section that supports the overhead conductor, and the underground section (i.e., structure foundation) that supports the aboveground structures and the conductor.

4101: The Business Case for Herbicide Use in Integrated Vegetation Management Programs

This study compares the cost of maintaining vegetation on electric transmission right of way (ROW) corridors with and without the use of herbicides. Species of trees within electric utility's ROWs have the potential to grow into conflict with overhead electric utility lines and are incompatible with the intended land use. Electric utilities throughout North America maintain vegetation within the ROW by controlling the growth of incompatible species. Three case studies were used to compare the co

50166: Mitigating Distribution Overhead System Risks Associated with Wildfires

Electric utility facility involvement in the ignition of wildfires is not uncommon, and unfortunately, the frequency and severity of catastrophic wildfires attributed to utility infrastructure is rising. Historical data indicate that wildfire ignition risk is significantly higher for overhead distribution infrastructure than for transmission and substation facilities, and wildfire damage to distribution equipment typically results in prolonged outages. With the increase in severity, electric uti

50149: Impact On Worker Safety Of Distributed Energy Resources Connected To The Distribution Grid

Distributed Energy Resources (DERs) are being installed at an accelerated rate, and utility concerns are rising as to the safety impact of this new technology. Multiple sources of energy that are not directly controlled by the utility and power from unusual sources are among these new concerns. The objective of this project is to identify effective practices for maintaining an acceptable level of worker safety in the presence of DER connected to the distribution grid. The research documents seve

0118: Operation and Maintenance Issues with Advanced Combustion Turbines

This report explains the growth of advanced technology combustion turbines (CTs) installed and operated in North America. It tracks the growth of the industry since 1985 and the changes that have occurred. While the report concentrates on operation and maintenance issues (O&M) associated with these CTs, other issues, such as the impact of high natural gas prices on the O&M costs, are discussed. It is noted that these advanced turbines can generate power at efficiencies approaching 60% (LHV Basis

3328: Development of Common Structures for Emergency Restoration

Restoration of electrical systems after recent large ice storms, hurricanes and other wind storms has demonstrated the need to have structures on hand for the emergency restoration of high voltage transmission lines. This project provides an overview of the experiences and preferences of the participants of the CEATI Overhead Line Design Issues & Wind and Ice Storm Mitigation Interest Group (WISMIG) with respect to emergency restoration and the general types of structures that may prove useful a
