5045: Technical Requirements to Help Formulate a Polymer/Composite Cutout Specification

The project consisted of formulating a Technical Product Requirement Specification that will help utilities jump-start the writing of a future North American polymer/composite cutout standard. A brief history of past problems associated with porcelain cutouts is presented to help better understand their specific reasons for and modes of field failure. The project scope included a brief literature review of available technical information to establish a base from which to work regarding composi

3202: Steel Tower Grillage Condition Assessment Methods

This report details the results of a literature review of the current state of the art in assessment methods for evaluating the condition of tower leg grillages in electrical transmission systems. The techniques reviewed included visual inspection, ultrasonic thickness measurements, long-range ultrasonics, time domain reflectrometry, ground penetrating radar, magnetic flux leakage, potential measurements, copper sulphate half-cell monitoring, linear polarisation resistance, electrochemical imped

0155: Thermal Power Plant Changes and Modifications in Order to Burn Carbon Free Fuels

This project explores the use of Carbon Free Fuels for thermal power generation. The analysis looks at using such fuels the main fuel source as well as blending with existing carbon-based fuels (as a start). The report discusses the power plant changes and modifications required to implement alternative fuels. The review also looks at the operations and maintenance implications of such a conversion, and provides insights on the impacts of various operating modes such as base loading, cyclic and

3735: Guidelines and Training on the use and application of Clamp-on Ground Testers

This project investigated the theory behind ground resistance measurement using one of the most recent and convenient devices available in the market. A clamp-on ground resistance meter is a relatively small piece of equipment that measures a ground grid’s resistance by clamping the device around the electrode being tested without detaching the electrodes from the system. Since this device is relatively new and different from other grounding test equipment, operators might misunderstand its read

0552: Battery, Solar and Wind End of Life Management

Renewable energy resources, such as wind, solar, and batteries, have become increasingly prominent over the past 20 years. Although some emissions can be associated with the manufacturing and construction of these projects, the long-term operation of these renewable energy projects generally results in a very low carbon footprint. However, the sustainability of decommissioning wind turbine blades, solar photovoltaic (PV) panels, and lithium-ion batteries poses significant challenges. These compo

3245: Methodology for Integrating New Technologies in Asset Management Practices

A number of new technologies have been developed to help electrical utilities in addressing the numerous challenges associated with managing and growing their power network while facing rigorous financial constraints and increased level of scrutiny by customers, regulators and other stakeholders. This report presents a consistent approach for integrating such new technologies into established utility’s practices. Case studies describing a step-by-step process for integrating three differen

50153: Framework for Deriving Failure Probability Functions for Underground Cables

Underground cables typically represent assets that carry an elevated risk within the distribution system when compared to other distribution system assets. There are limited inspection and maintenance practices that can be actively performed for underground cables to further extend their useful life, due to the fact that these cables are typically contained underground – either direct-buried or in conduit – and possess limited accessibility. Furthermore, the outright replacement of c

3317B: Evaluation of Live Line Conductor Vibration Recorders, Part I: Bench Tests

Aeolian vibration of overhead transmission conductors can lead to fatigue damage. The fatigue damage is evident by broken strands at the suspension clamp of the conductor. Field vibration recorders are used to indicate the stresses that result in fatigue damage by measuring the bending amplitude at the conductor’s suspension clamp. The bending amplitude is relatively small, in the range of 0.25mm (0.01 inch). The task of the vibration recorder is to measure these small amplitudes in a very

5080: State-of-the-Art Review of Management of Technical and Non-Technical Losses in Distribution Systems

The objective of this project was to review and summarize practices of leading distribution utilities and to recommend effective “good utility practices” with respect to management of technical and non-technical losses. Information on the extent of losses and practices with respect to loss management was obtained by means of an extensive literature search and analysis, and a survey of distribution utilities in North America, Europe and Australia. Techniques to estimate system technic

0237: Dam Safety Essentials for Engineers

The Dam Safety Essentials Guidance and Training for Engineers project (Project) provides dam Owners with a framework and materials for delivery of dam safety training to engineering and technical personnel. The Project builds on but is independent of the Dam Safety Inspection Procedures, Guidance and Training for Plant Operators training materials (CEATI Project No. T112700-0227), which provide a broad introduction to dams, failure modes, and dam surveillance and monitoring. The Project was conc
