3105: Transmission System Planning and Operation under Uncertainties, Phase I

This project identifies available tools and techniques for transmission planning and operation that include the uncertainties of generation and load conditions. While transmission system operators address these issues in various ways around the world, there is no commonly accepted, comprehensive approach. The application of probabilistic tools for scenario analyses is a method for addressing the uncertainty of unavailability and load growth. For transmission planning, composite reliability asses

5074: State-of-the-Art Portable Mega Ohmmeter Comparison

This report critiques the suitability and adequacy of commercially available Mega Ohmmeters for testing various pieces of equipment installed on overhead and underground distribution lines with nominal system voltage ranging from 4 kV to 35 kV. While establishing suitability of meters, characteristics related to safety, compactness, portability, ruggedness, and reliability in providing sufficiently accurate measurements have been taken into consideration. The report also documents the criteria f

3225: Best Practices for Transmission Line Inspections and Recommended Inspection Techniques

This project is intended to provide utilities with the information they need to assess and compare their current inspection programs to the best practices of the industry and modify any areas that will lead to improved effectiveness of their inspection programs. The scope of the project focused on the following main tasks:1. A survey of utilities was conducted to document transmission line inspection practices, identify the various classes of inspection (overview, condition, climbing, infrared,

33126: Selection Criteria of Backfill Materials and its Impact on Assessing Foundation Capacity

This report provides a state-of-the-practice assessment of commonly used and alternative backfill materials for the design and construction of direct embedment poles installed in drilled holes (shafts), grillages, and pad and chimney foundations for the electric transmission industry. The challenge associated with backfill materials derives from the need to achieve a specified in place density so that a foundation functions as designed. In addition to the confined spaces where backfills must typ

5060B: Remedial Treatment of Utility Poles Using Borate Rods and In-Situ Butt Encapsulation, Phase II: Initial Setup and First Sampling

This project investigates the efficacy of the chemicals identified in Phase 1 by doing field tests on aged pole butts from poles removed from service. The butts are set in a test plot and treated with the potential barrier formers and borate rods will be introduced at the ground line. At selected time intervals (e.g. 3.5, 5, 8, and X years) specimens are removed and sectioned into eleven 4-inch thick slabs (one slab from above ground line and ten from below). All slabs will be stained to show bo

3417: Guide for Development of Business Cases for Replacement of Transmission Cable Assets

Many cities around the world experienced significant growth after the end of the Second World War. Utilities began rapidly installing underground transmission cables in major cities and urban areas to plan for future demand. Many of these first generation cables are still in service but will soon reach or exceed their expected design life. Since cable replacement costs are extremely high, utility engineers and asset managers are required to provide a detailed justification for these replacement

50127A: Assessment/Test Methodology of In-Service Pole Line Anchors

This report reviews different types of anchor rods, the predominant failure mechanism and methods for condition assessment. Information was gathered through literature reviews, a utility survey and an evaluation of the effectiveness, cost and sensitivity of condition assessment methods. Anchor rods are used in electric utility overhead transmission and distribution (T&D) systems to support dead-end or angle poles as well as guyed transmission towers.The anchor rod is typically the limiting facto

0518: Strategies for Energy Utilities to Address Emerging Sustainable Neighbourhood Development Trends

The landscape is shifting for utilities in North America as a result of market deregulation, the convergence of electrical and natural gas fuel options, the advent of new technologies, and the rise of sustainability and climate change as drivers of consumer choice and public policy. As a result of these changes, developers, municipalities, and new competitors to traditional utilities are, often collectively, creating ultra-low energy communities that utilize alternative energy technologies.
