3423: Advanced Cable Diagnostic Test Techniques for XLPE, HPFF and LPFF Cable Systems

There are several test techniques offered in the industry for evaluating high voltage (HV) cable systems. There have been presentations made at technical meetings organized by the IEEE Insulated Conductor Committee (ICC) and CIGRE regarding the field testing and diagnostics of HV cables.Some of the diagnostic test techniques are relatively new to the industry and have not necessarily been verified for suitability. This project was undertaken to highlight the different types of diagnostic tests a

0528: Torrefied Biomass Vendor Assessment Study

This study assesses the current vendor and technology landscape capable of producing torrefied or carbonized biomass designed specifically for consumption in utility scale coal-fired electricity generation plants. The analysis first provides a technology and market overview and then evaluates eight biomass torrefaction vendors, detailing the particulars of each vendor's production process, current and planned capacity, production capabilities, and end-product specifications. A concluding section

5056: Development of a Fault Alert Device for Distribution Transformers

This report describes the design, development and testing of two alpha-prototypes of the Fault Alert (FA), a device intended as an accessory for the fuse cutouts that is capable of detecting and signalling the presence of the low-impedance internal faults in distribution transformers.The FA was conceived as a high impedance current sensor that connects the transformer to the power system once the fault current has been interrupted by the fuse. When there is no internal fault minute current flowi

4301: Health and Safety Management Best Practices Guideline

This guide defines a proactive approach to managing workplace health and safety (H&S). Most approaches have typically been reactive in nature, where actions have been taken once an employee is injured or becomes ill. Finding and fixing hazards before an employee is injured or becomes ill is a more effective approach and promotes a more positive work environment.This guide is based on industry best practices and is consistent with international standards. The level of detail and complexity of

5029: Remaining Life Estimation of Distribution Transformers

Remaining life estimation technologies of transformers have been examined by reviewing technical publications, national and international standards, and surveys of North American utilities. Remaining life estimation was examined from the point of view of condition assessment, available existing and emerging tools, and statistical, deterministic and economic methods. Most utilities make use of visual inspections, company standards and in-house expertise, and a few electrical or oil tests, to deci

3026: Prediction of the Remaining Life of Power Connectors and Disconnect Switches

The work reported here is comprised of the identification and quantification of the limits of the major parameters determining the quality and life of power connectors and disconnect switches and a detailed description of degradation mechanisms/failure modes and their effects on the ability of power connectors and disconnect switches to perform their design functions. Also included in the report is an in-depth description of the effectiveness of various palliative measures used to limit the dele

3208: Live Inspection Techniques to Detect Conductor Wire Breaks at Suspension Clamps

This report deals with a feasibility study which aims at determining whether broken wires atsuspension clamps of overhead stranded conductors could be detected by means of microohmmeterslooking for changes in local micro‐resistance. Two commercial instruments were testedin that regard, the DRM‐40 and the Ohmstik ohmmeters, within the frame work of a mini‐testprogram involving a Mallard 30/7 ACSR conductor, strung over a 30‐m outdoor test span, carryingan AC current or not, either in the intact c

30122: Enhanced Diagnostics and Condition Assessment of LTCs

Although progress has been made over the last 20 years, there still remain unresolved problems with load tap changers (LTCs) that need to be addressed. In particular, coking of LTC components remains a major problem. There is currently no non-invasive method to determine the inception of coking, its presence and severity, and its relation to LTC make and model.This report summarizes the research findings of a study which used a small scale LTC model to carry out accelerated LTC operations. The o
