33112: Guidelines for Compact Line Design

Utility experience in the past few years has shown the possibility to eliminate the impact of transmission lines on the community by implementing techniques such as compact lines. The major motivation for the implementation of compact lines is that by using conductors that are spaced closer together and supported by smaller and more attractive structures, overhead transmission lines will be less visually intrusive and more likely to be accepted by the public.CEATI awarded project # T173700-33/11

3123: Criteria for Tapping Bulk System Transmission Lines for Load Supply and Generation Connection

Transmission line taps can be a more economical way of interconnecting load and generation than construction of new switching stations or new transmission lines to existing switching stations. Recognizing that virtually any tapped connection to a transmission line will degrade the reliability of the line to some extent, the question arises as to how to identify whether or not the degree of degradation will be acceptable. This report investigates the factors that are used to evaluate the a

50111: Distribution Roadmap Update

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

3016: End of Life Decision on Circuit Breakers

The objective of this project was to develop a detailed, structured, quantitative methodology (model) to rank a diverse population of circuit breakers in order of proximity to End of Life (EOL).By means of a literature survey, discussions with technical experts, factors and information, are identified which should be included in the decision support model, based on what data is reasonably available within a member utility.Information is translated into groupings, with appropriate weighting facto

3726: Mitigating Step/Touch Voltage Safety Associated with Buried Objects Near Substations

Expansion of municipal services in major cities has resulted in buried and touchable metal objects such as chain linked fences, street lighting poles, and pipelines being placed near energized substations. Electric utilities often have little control regarding the placement of municipal infrastructure and services. These metal objects are subject to step and touch potentials that might pose risks to public safety and the reliable operation of electrical equipment. Existing standards such as IEEE

5143B-02: Overview of Voltage Variations

ABSTRACT: Voltage sags and momentary interruptions are often the most important power quality problem for customers. These conditions are characterized by short duration changes in the rms voltage magnitude supplied to the customer. The impact on the customer depends on the voltage magnitude during the disturbance, the duration of the disturbance, and the sensitivity of the customer’s equipment. Voltage sags and momentary interruptions are inevitable on the electric power system. The most

50121: Bonding of Telecommunications Sheath/Messenger to the Power Neutral

A telecommunication line parallel to an overhead or underground power distribution line is subject to electromagnetic induction from the power system under both normal loading and fault conditions. In order to minimize the possible hazards and damage caused by the electromagnetic coupling from the power system, bonding of an overhead telecommunication messenger or underground communication cable sheath to the electric utility’s neutral is common practice.This project studied the electromag
