50154: Innovative Techniques to Reduce O&M Costs

The pressure to reduce costs and improve utility operations is ever present. Innovative concepts are regularly presented, and each comes with the same question: “Does this apply to us?” This report examines some of the innovative techniques currently being evaluated by utilities.Innovations are often presented from a vendor or service provider point of view with little evidence of effectiveness from utility experience. Therefore, there is a need for utilities to share experiences wit

50152: Detecting High Impedance Faults on Overhead Distribution Systems

High impedance faults (HIFs) are short-circuit faults that do not produce sufficient fault current and are thus not detectable by traditional overcurrent protection schemes. Research on HIF detection has been ongoing since the 1970s. Unfortunately, progress has been slow due to the complexity of HIF characteristics. This project conducted a comprehensive survey on the characteristics of HIFs and various HIF detection techniques. The techniques can be broadly classified into three types: 1) techn

50157: Application of Energy Storage Technologies in Power Distribution Systems

This report reviews energy storage (ES) technologies and assesses them based on several technical metrics. Potential applications of the technologies in distribution system are identified, categorized, and discussed. Real-world examples of utility-scale ES deployment use cases and experiences are presented. In addition, two case studies on key energy storage applications in distribution systems are conducted and technical parameters are determined. This report will help utility engineers gain a

5005: Validating NDE Tools for Evaluating Present Condition, Residual Strength and Remaining Life of In-service Wood Poles

The effectiveness of eight different inspection tools were evaluated through field inspection of 60 distribution size wood poles ranging in age from 2 years to 54 years. The conventional inspection method was evaluated as well. The results of these inspections were compared with results obtained from destructive tests, and the serviceability of the poles was assessed. The eight inspection tools that were tested measured one or more parameters related to condition, strength and/or remaining life.

5069: Cost of Reliability Methodologies

Electric utilities, facing a significant investment in their respective infrastructure, are increasinglyinterested in accurately identifying the cost of power interruptions and fluctuations in power quality(power‐quality events) to consumers as well as to their respective organizations. In this report, anintegrated model is presented to consistently determine the cost of reliability (i.e., the cost of electricservices interruptions) to utilities and their customers. The model provides the means

1005: Maximizing Value from Electric Transportation

This study is tailored to provide specific and valuable guidance to electric utilities of all types related to the electric transportation transition and its potential risks, costs, benefits, and value. This guidance will support concrete and immediate next steps for utilities, as well as a pathway to ensure maximum benefits from transportation electrification for electric utility customers and communities, while also distinguishing the requirements between residential and commercial/industrial

50104: Non-Wood Crossarm Electrical Testing Requirements

The project consisted of formulating a set of electrical performance based design tests that will help utilities in the writing of a future North American standard for rectangular-shaped non-wood or composite crossarms. Some possible modes and mechanisms associated with composite crossarms field failures are presented to help better understand reasons for formulating electrical design tests. The project scope included a brief literature review of available technical information to establish a ba

5071: Non-Destructive Condition Assessment of ACSR Distribution Conductors

This project, Phase 2, is a continuation of Phase 1 Non-Destructive Condition Assessment of ACSR Distribution Conductors – Phase 1 in 2003-04. Phase 1 work was completed in 2005 and is documented in CEATI Report T044700-5040. The objective of Phase 2 of the project was to develop a prototype device or to modify an existing device to inspect, in a practical manner, the condition of ACSR conductors on distribution lines. A prototype device has been re-engineered and fabricated based on infor

3710: Review of Distribution System Grounding Practices and Rules

Distribution systems have faced substantive and significant changes over recent years as a result of an increase in non-linear loads, the connection of distributed generation, a growing mindfulness for the protection of dairy animals against stray voltages, as well as the need to improve efficiencies and controllability. In response, designers are making changes to topologies, adding new protection and control devices, increasing distribution voltage levels, and paying more attention to neutral

5063: Implementation Roadmap for Utilities Deploying BPL Networks

Broadband over Powerline (BPL) is a technology that uses the electric utilities’ distribution networkas a transmission line for broadband access services including Internet, Voice over IP (VoIP) andVideo. These services can be provided by a telecom partner or by a non‐regulated subsidiary of theutility. BPL can also provide a communications network on the utility’s distribution network fordistribution automation applications.This report provides a Roadmap for utilities consideringimp
