5057C: Electric Distribution Utility Roadmap: The Case for Change

In Phase I, an Electric Distribution Utility Roadmap report was released in January 2004, to providea view of the evolution of the electric distribution utility environment over the next 20 years.The objective of Phase II is to develop an actionable plan from the Phase I Technology Roadmap thatcan be followed by the distribution utilities to justify and implement the technology initiativesrequired to meet current and future business needs.The approach for this phase involved initiatingthe follow

5030: Improved Performance of Switched Capacitor Banks

A review of available technologies was undertaken to determine if there are economical methods for monitoring and detecting out-of-service capacitor banks in non-SCADA equipped systems, and whether the installation of such systems can be economically justified.

5092: Satellite Technology Applications for Monitoring Electric Utility T&D Assets and Rights-of-Way

A review of the potential applications of Earth observation satellites was carried out for the benefit of the electric utility industry to determine the feasibility of using the technology in its operations. Focusing on nine specific activities that usually make use of aerial photography and other forms of detailed geospatial data/information, the study provides examples of potential applications and assesses their likelihood of implementation and the forecasted barriers to their introduction.

5079: Arc Flash on a Utility System

An arc flash on a transmission or distribution system results in high energy emission, mostly in the form of heat energy. This may present a concern to the safety of employees in the vicinity of the arc flash in open areas such as overhead lines, electrical distribution equipment, panels or substation equipment. A thorough understanding of arc flashes is necessary to accurately model them for identifying potential electrically hazardous areas, developing safe approach distances, and selecting th

5040: Non-Destructive Condition Assessment of ACSR Distribution Conductors

The rates of deterioration of specific distribution line components, such as conductors, are largely unknown and therefore as lines continue to age, their remaining physical life becomes of increasing concern, bringing to the forefront issues such as public and worker safety, competition, reliability, availability and system planning. Consequently, the desire to assess the actual condition of all line components is also increasing. Conductors are of primary interest because their condition often

5075B: Worker Protection on De-Energized Distribution Lines - Phase II

Protective grounding is employed to protect power line technicians working on a de-energized distribution line from electrical hazards. The electrical hazards are: (1) accidental energization, and (2) induced currents from nearby energized lines. In this project, the effectiveness of protective grounding in protecting power line technicians from these hazards is assessed in detail. This project also addresses the effectiveness of protective grounding methods to protect against the current inject

50118B: Distribution System Health Indices: A Simplified Methodology

This project 50/118 developed simplified health index algorithms based on existing best practice algorithms to calculate health indices where the full set of condition parameters is not available. The algorithms were tested for sensitivity and applied to real-world failed asset data. The resulting study revealed that a “gateway” model is better suited to applying health indexing to assets with critical condition issues. Based on the “gateway” methodology, a “simplif

5010: Evaluation of an Environmentally Benign Borate Preservative Treatment to Control and Prevent Internal Decay in Electrical Utility Poles

The relative mobility of an organically borne borate wood preservative and methylisothiocyanate in wood was evaluated under dry climatic conditions. Western red cedar and lodgepole pine stubs cut from dry pole tops were treated internally with the preservatives and the migration of the active ingredients was measured over a one-year period. Methylisothiocyanate traveled 90 cm above and below the application point within one month after treatment. The movement of the borate solution was much slow

50132: MicroGrids – Opportunity or Threat for your Distribution System

The integration of microgrids may open up new opportunities for utilities or pose threats to their conventional business model. This issue is explored in depth with attention given to existing and potential microgrid deployments, including various microgrid configurations as well as the ownership and operators. DNV GL developed this report based on its extensive experience researching and analyzing the technical and economic impacts of microgrids for various stakeholders, from customer-owners to
