3244: Tool to Assist Utilities with Prioritizing Lines to be Inspected, Setting and Refining Inspection Intervals, and Selecting Diagnostic Methods to Implement

This project was designed to develop a spreadsheet-based tool to objectively prioritize which transmission lines to inspect, to establish appropriate inspection cycles, and to identify line inspection and assessment methodologies. The project will benefit transmission utilities by providing a resource to facilitate informed decisions making regarding allocation of inspection resources which should in turn enhance the cost-effectiveness of maintenance and ultimately aid efforts to improve transmi

3032: Survey of Existing Multi-Criteria Substation Equipment Asset Management Methods

The objective of this project was to identify and evaluate the performance of Multi-Criteria Decision-Support (MCDS) tools and methods, which have been successfully used by electrical utilities and similar entities to make optimized decisions on continued operation, restoration, refurbishment, replacement, and run-to-failure policies for utility equipment, specifically substation assets.By means of a literature search and critical review, a focused survey and follow-up interviews with users of M

5053: Metal Streetlight Pole Inspection Standards

A study was conducted to develop an inspection standard and to define the skills required to perform condition assessment of thin walled metal streetlight poles. An in-depth literature search and an industry survey were carried out to review the current status of inspection standards and to recommend promising new techniques.

5170: Guide for Coordination of Electrical Distribution Feeders and Gas Pipelines

The primary objective of this study is to prepare appropriate criteria and recommendations to consider for the safe coordination between pipelines and electrical distribution utilities sharing the same corridors. Industry trends have resulted in an increasing number of shared right-of-ways (ROWs) between gas and electric utilities. The increased focus on shared ROWs is the result of several factors including permitting, topography, land access, and urban sprawl. AC interference on pipelines from

3508: Key Management

A critical component of physical security is key management. The management of keys has historically been poorly controlled within electrical utilities. Card access is partially replacing the installation of mechanical locks but in many cases conversion to electronic card access control is not practical. The objectives of this report are to identify approaches to key management and to develop recommendations for best practices that can be applied to the full range of access-control needs of elec

5131B: Stray Voltages in Higher Load Density Environments-Causes, Effects, Measurement and Mitigation Techniques

This document describes procedures and equipment suitable for conducting consistent and repeatable evaluations of publicly and privately accessible contact voltage situations in higher load density urban environments. Although useful measurement protocols and procedures exist for some situations, such as measurements in animal contact areas, there are inconsistencies and differences in the procedures used to conduct assessments of contact voltage across some of the other areas of interest. To th

5011: Ultrasonic Detection As A Predictive Maintenance Tool For Cable Accessories

This report describes work performed to evaluate ultrasonic detection as a tool for locating partial discharge in distribution cable accessories. The evaluation was done by conducting laboratory and field tests on a commercially available ultrasonic detector which had been modified by adding an electrically insulated contact probe. Separable insulated connectors, which consisted of elbows, bushing inserts, and junction bars, were modified to produce partial discharge to simulate typical failur

0349: Identification of Hydro Performance and Production Problems Including Start-Stop Operations

As a result of a continually changing operating environment for hydroelectric generating (hydro) assets, the Hydraulic Plant Life Interest Group (HPLIG) and other groups have been monitoring the reliability and availability of assets within their purview, looking for a broader comparison of reliability reporting systems, potentially for standardization, and also looking for relative performance assessments of units on a broader comparative basis.Additionally, asset owners are keenly interested i
