3021: Safety Protocol for the Detection and Cleanup of SF6 Gas and SF6 Gas Decomposition Products in Buildings Following Catastrophic Failure of SF6 Gas Insulated Switchgear

Phase I: This report provides the background and reference in support of a safety protocol for the detection and cleanup of sulphur hexafluoride (SF6) and SF6 decomposition products following a catastrophic failure involving indoor gas insulated substations (GIS). The latest field methods for the detection of SF6 and SF6 decomposition products were identified in this phase. Case histories of previous incidents were discussed and a summary compiled of the nature and quantities of decomposition pr

3424: An Assessment of Technologies to Permit Safe Entry into Vaults and Manholes with Energized Equipment

Work performed in underground electrical vaults is typically performed with all equipment in a de-energized and isolated state. There are some circumstances when emergency work must proceed in the vicinity of energized medium (MV), high voltage (HV), and extra high voltage (EHV) equipment and this introduces several significant hazards to workers even when time spent inside the vault is minimal. Safety procedures should include methods of identification, discrimination, localization, and assessm

50130: Current Practices and Future Trends in Distribution System Hardening for Extreme Weather Events

As climate experts warn of a continuing trend towards more severe and frequent extreme weather events, it is unclear whether existing utility codes and design standards are keeping pace with these potential changes. This report examines the issue of distribution system hardening for extreme weather events. Included are the results from a survey of several member and non-member utilities regarding their perception/history of extreme weather event frequency and severity, along with any modificatio

50113: Impact Of A Protective Coating Against The Effect Of Road Authority Chemicals And Atmospheric Pollutants On Different Assets Of The Distribution Network

Electric utilities are facing an aging of their equipment over time. The life expectancy of different equipment may be affected by factors other than normal aging. This premature aging of different equipment leads to higher cost of maintenance and/or replacement of equipment. This report looks at the effect of de-icing salts and atmospheric pollutants on premature aging of certain electrical equipment and describes some mitigation methods that are currently used by the utilities. Finally, the la

50146: Technical Recommendations for Solar Distributed Energy Resource interconnection Analysis

Utilities in the U.S. and Canada are experiencing a rapid expansion of solar photovoltaic (PV) installations on their distribution systems. These installations are often not monitored or controlled by the utility in the same way as conventional generation, which can lead to technical and operational challenges for the distribution system and sub-station equipment. This work describes a methodology for addressing some of the potential issues associated with increasing levels of PV on the distribu

50106: Assessment/Test Methodology Of In-Service Electrical Connectors For Overhead Lines

Utility distribution systems utilize a variety of connectors to join and attach overhead conductors. Factors such as corrosion, improper installation, and manufacturing defects can cause in-service failure of connectors, leading to safety risks for both crews and the general public, and compromising the reliability of the power supply. Many utilities have experienced this problem and made tremendous efforts to mitigate the risk. However, due to the nature of the connector design, these defects a

G644: Technical Options For The Disposal of CFBC Solid Wastes

Circulating Fluidized Bed Combustion technology is amongst some of the most advanced acid gas emission control technologies. Although the reduction of acid gases is accomplished by this type of combustion, the generation of solid residues has become an area of concern. Much research into FBC technology and FBC wastes has occurred over the last ten years, resulting in improved disposal methods and possible uses for the residues in commercial products. Some of these previous studies dealt with lan

4201: Library of Key Performance Indicators (KPIs) for Transmission and Distribution Assets

Measuring the success of asset management plans is typically done through reporting against a set of Key Performance Indicators (KPI’s). Over the years, transmission and distribution (T&D) electric utilities have developed numerous KPI’s of varying usefulness. This project first collected industry-standard T&D KPIs, and these were augmented with contributions and input from the CEATI T&D Strategic Asset Management Program utility participants to create an initial library of customize

0334: CPF: Technology and Tools for Reduced Operations and Maintenance Costs

To increase hydroelectric plant maintenance managers' awareness of current technologies and equipment related to the management of forebay debris, a Technology Review (TR) of the state‐of-the‐art in equipment was undertaken, under the auspices of the Hydraulic Plant Life Interest Group. This report has two main focuses: trashracks and trash removal tools (principally trashrack raking equipment).Several sources of information were used, including solicited information from hydro industry service
