50139: Asset Management Practices for Distribution Utilities

The primary objective of this initiative was to update CEATI Report T044700-5055 “Asset Management Practices of Leading Distribution Utilities” that was published in April 2006. The focus of the project was to update the information pertaining to asset management practices of DLAM Utilities to learn more about the current state practices and what has changed since the original report was published.Keywords:Distribution Utility Asset Management Practices, Distribution Asset Management

33108A: Impact of Climatological Influences on Overhead Line Design

Climate change imposes increasing threats to national and regional power networks, particularly to overhead transmission lines. In a changing climate, the frequency and severity of extreme weather events as well as the mean state of the atmosphere will change; this affects overhead lines, as they are typically designed to take the current or historic climate into account. There is therefore a strong need to quantify the relevant changes in the climate and any the associated uncertainties as well

3274: Information Required to Manage the Life Cycle of Transmission Line Assets/Components

With the onset of more formal data-driven asset management practices, utilities have taken steps to enhance their data collection and information requirements. However, in some cases, this has resulted in data collection practices that are not aligned with the evolution of asset management and continuous improvement, resulting in uncertainty as to what is the right, and right amount of, information for the life cycle management of transmission line assets/components. This project is intended to

3044: SF6 Gas Handling While Maintaining High Voltage Switchgear

Sulfur Hexafluoride (SF6) is a nontoxic gas utilized for its high dielectric capabilities. When subjected to extreme heat, such as short circuit faults, SF6 can decompose to hazardous byproducts. These byproducts can cause medical injuries if mishandled. In May 2005, CEATI published Report T023700-3021 entitled “Safety Protocol for the Detection and Cleanup of SF6 Gas and SF6 Gas Decomposition Products in Buildings following Catastrophic Failure and Release from Indoor SF6 Gas Insulated Sw

3348: Assessment of Aged Conductors and Shieldwires - Phase I: The Process

Many overhead transmission and distribution lines in North America have far exceeded their design life. Consequently, the desire to know the actual physical condition of transmission and distribution line components is increasing. Many utilities base condition on age alone, however this can be misleading. Physical assessment through field and laboratory evaluation is the only way of knowing the current condition of conductors and shieldwires with any degree of reliability and accuracy. This

5141: Impact of Utility Voltage Variations on Customer Systems: An Application Guide

The objective this project was to develop an application guide which provides a review of voltage variation phenomena that can negatively affect utility and customer power systems. The guide includes relevant standards-related information and representative waveforms for many of the common voltage variations that occur on the electric power system, including voltage sags during transmission and distribution system faults, momentary interruptions during circuit reclosing, undervoltages during in

3725: Guidelines for Grounding of Customer HV Installations

Independent consulting companies are increasingly designing grounding at customer and utility owned stations. Inconsistencies in these designs and misinterpretations of requirements have, at times, due to the variety of guidelines and standards, resulted in parochial jurisdiction and differing approval processes. Examples include questions of whether pad mount transformers constitute substations, whether credit may be assumed for connections to overhead ground wires and neutrals owned by differe

3101: Fault Current Management

Faults expose power apparatus to large short-circuit currents, potentially causing damage due to the associated mechanical and thermal stresses, both of which increase with the square of the current. While fault duties can be held down by system design, such measures inevitably compromise operational reliability and system efficiency. Thus a device capable of limiting fault currents within the first half-cycle has been sought since the 1970’s, when fault levels had already reached 60-80 ti

3372: End of Life of Wood Components

Due to their inherent advantages, wood poles and wood components (e.g. cross arms, braces) have been used exclusively for transmission line support structures for over 100 years. At the present time, there are millions of wood poles and wood components supporting transmission lines at voltages of 69 kV and above. However, some of these structures have degraded due to biological degradation, bacterial attack, fire damage, woodpecker attacks, etc. This report deals with the condition assessment of
