G789: Development of An Instrument To Detect Partial Discharges In Thermal Alternators

A new test has been developed which enables utility maintenance personnel to evaluate the high voltage stator winding insulation in turbine generators and large motors. The test allows plant staff to measure the partial discharge activity while the generator or motor operates normally. Partial discharges are a symptom of most stator winding insulation problems.The test requires the prior installation of special sensors, either stator slot couplers or bus couplers, on the machine during an appr

G912: Automatic Wildlife Tracking/Monitoring System - Phase II

The goal of this study is to design a GPS system capable of addressing, in a reliable and cost effective manner, habitat/resource utilization by large mammals (moose and caribou) on and in the periphery of the reservoirs, in heterogeneous environments, and along corridors such as large rivers and power distribution rights of way.The objectives have been formulated to complement and enhance our remote sensing technologies which have been used to collect reliable and accurate biological informati

U551: Forecasting Peak Load

The objectives of this study are to identify existing techniques for forecasting peak load requirements five to twenty-five years into the future, to evaluate these techniques and recommend those most applicable to the Canadian setting, and to propose any modifications that may be required by specific Canadian utilities to incorporate these techniques. These objectives were met by undertaking a review of literature on peak load forecasting techniques, an evaluation of the techniques currently av

T716: Electrical Breakdown Characteristics of Oil-Paper Insulation Under Steep Front Impulse Voltages

The electrical breakdown properties of oil impregnated paper insulation under steep front impulse voltages were studied. The data collected were used to develop a statistical model to predict the probability of failure for arbitrary transient voltage waveforms. The model was tested with various waveforms in uniform and non-uniform field configurations, and was found to be satisfactory.This provides the capability of estimating the probability of failure for transient waveforms such as those ge

D917: Characterizing the Overcurrents on Distribution Systems

Overcurrents on distribution systems include permanent faults, temporary faults and other lower magnitude surges, typically from switching events. The overcurrent environment of the distribution system must be quantified in more detail if distribution system power quality and reliability improvements are to be made. New and more complex overcurrent protection products require more exact knowledge of feeder conditions. In the absence of today's data acquisition equipment and computer simulation

G303: Measuring Boiler Tube Wall Thickness in Thermal Power Plants Using Electromagnetic Acoustic Transducers

The objective set for this work was to design an electromagnetic acoustic transducer (EMAT) for in-situ measurement of boiler tube wall thickness, in power station heat-exchangers, where the presence of scale on the tube precludes the use of piezoelectric transducers.Stage I of the project covered the design criteria for the electromagnetic acoustic transducer (EMAT) and the instrumentation required to collect and process the data. This report covers Stage II of the project but includes also a s

U770: Multi-Storey Solar Illumination System for the New Market Lane School

This report focuses on the implementation of a multi-storey solar illumination system which is capable of providing illumination deep within a building's core. In particular, this report describes the installation and performance of a unique solar illumination system which has been installed in Toronto Board of Education (TBE) Market Lane school facility in downtown Toronto.This goal was achieved through the development and installation of; several large capacity heliostats, efficient light tran
