5032: Extended Application of Internal Fault Detector

This report describes opportunities to extend the application of the Internal Fault Detector (IFD) technology to additional electric distribution equipment. Currently, the IFD product provides a visible warning to line crew personnel that an overhead transformer has developed an internal fault, so that they will know it poses a risk of creating a hazardous event if reenergized. In the two most attractive new applications identified, however, the IFD was regarded mainly as a troubleshooting aid.I

5044: Evaluating the Energy Efficiency of Distribution Systems

Cost-effective methods of estimating the energy efficiency of distribution utilities have been developed and implemented in spreadsheets. A typical range of values has been established for different types of service territory, 2 to 5% in urban areas and 4 to 10% in rural areas. Methods of reducing energy losses on distribution systems are discussed in terms of effectiveness and cost. The simplified loss analysis method presented in this report can be used to identify and prioritize the major c

3137: Maintenance Best Practices for HVDC Lines and Converter Station Equipment

This report presents a best practices guide for maintaining electrical equipment at HVDC stations. It is intended to be used by utility personnel involved in the daily operation and maintenance of the electrical equipment. As a means to both directly highlight the most important and common maintenance items, as well as record the maintenance information itself, a maintenance checklist format was used throughout this document. Adding significant value, this document also includes survey results f

5132: Power Quality at Supply Points to Distribution Companies

This report identifies a set of primary Power Quality (PQ) Indices for monitoring at points of supply to distribution companies. The indices are reflective of international standards and also coordinate with existing guidelines of utility companies.The power quality indices developed in this report include target levels (often defined in terms of probabilities for a specific percentage and a specific time period), planning levels (design criteria or internal guidelines), and indicative levels (g

50136: Practical Roll-Out of Feeder Automation on the Distribution System

This paper focuses on Distribution Automation (DA), specifically “Feeder Automation” (as opposed to stations). The study draws from the available experiences of the industry's utilities and vendors, as well as the experiences and professional judgments of the Principal Investigators. The report identifies the risks and measures to implement a DA system from a practical standpoint that has proven to be successful in the past. A literature review of published standards, framework docum

3054: Substation Design Sharing Database

The objective of the Substation Design Sharing Database is to enable utilities to share their designs and provide a means through which participants may find solutions to design problems and also discover alternative designs for future consideration.The Substation Design Sharing Database was developed as a simple-to-use file-sharing site to organize substation drawings that participating utilities are willing to share with others. This CEATI Information Technology (IT) department has incorporate

5140: Uniform Practices in Reporting Momentary Outages and Their Relationship with Power Quality

The reporting of momentary interruptions and voltage sags has been examined to identify a single metric that is suitable for communicating the momentary interruption and voltage sag performance of the power delivery system in relation to the customer expectations of process equipment performance with large groups of stakeholders. The existing SARFI70 index with a small modification to the duration definition has been proposed, because it will result in a value that is in line with customer exper

3254: Measurement of cm-Scale Soil Subsidence and Structure Movement in Remote Areas Using Satellite Imagery

A pilot project on the potential applications of Synthetic Aperture Radar Interferometry (also known as InSAR) technology was carried out by Effigis Geo-Solutions in a test area of approximately 200 km2 located 30 km east of Winnipeg, Manitoba. The project aimed to assess the use of InSAR techniques to identify centimeter-scale vertical displacement in transmission line infrastructures and surrounding terrain. It involved the acquisition of 15 TerraSAR-X interferometric images in the summer-fall

5126: Customer Power Factor Correction Capacitor Application Guide

The objective of this project was to develop an application guide that provides design and application procedures for power factor correction within customer facilities. The guide presents technical and economic issues associated with power factor correction and illustrates some frequently encountered power quality and operational problems. The application of power factor correction capacitors increases system capacity and reduces system losses. Generally for industrial customers, power facto
