U808U: Investigation of the Risk Factors for Sporadically Occurring Legionnaires' Disease

The potential of acquiring Legionnaires' disease in the home environment was studied using a case-control design with 146 cases of Legionnaires' disease and 275 matched controls living in two counties in Ohio. By multivariate analysis, cases were more likely than controls to have Legionellae cultured from water sources in the home, to have non-municipal water supplied to their home, and to have had recent plumbing work on their home.Franklin county residents with underlying health conditions had

T372: Specification of Data Acquisition System For Load Model Parameter Estimation

The objective of this project was to arrive at a set of specifications for a system to be used for gathering data for load modeling. The requirements of Ontario Hydro and Hydro-Quebec along with the responses received from other utilities formed the basis for this specification. In order for wide acceptance and marketability, the system is also expected to perform related data acquisition tasks; in particular, it will calculate cycle average values of power system parameters during a disturbance

D333A: Performance of Wood Pole Species in Service 1990 Evaluation

This report presents the data collected on various parameters of wood pole samples examined in 1983 and 1990. These parameters included surface preservative retention both above and below the groundline, fungal population indentification, decay evaluation and other field information that directly influences the integrity of the pole, including checking, remedial treatment, mechanical damage, slope of grain, moisture content and soil type. All data from both field examinations were entered into a

G699: Metallographic Approaches To Creep Life Prediction For Thermal Power Plants

Surface replication is routinely used to detect creep cavitation and micro-cracking in high temperature components of thermal plant boilers and turbines. In this project, electron optical and image analysis techniques have been developed to expand the scope of replication into quantification of the subtle microstructural changes which usually precede cavity formation in low alloy steels. Carbide particle coarsening measurements can be used to derive the thermal history of the component; this is

G930: 75kW Utility Interactive Photovoltaic System at the Hugh MacMillan Rehabilitation Centre

This report describes three years of experience with large utility interactive photovoltaic systems at the Hugh MacMillan Rehabilitation Centre in Toronto. To date, the centre features 75 kW of photovoltaic power and is the largest concentration of photovoltaic power in Canada. Over the past several years, three 25 kW systems have been installed at the Centre under a joint research and development program sponsored by the federal and provincial governments and Ontario Hydro. Each system represen

T421: HVDC Wall Bushings

Two test methods have been developed to simulate conditions causing flashover of HVDC wall bushings at working voltage in service. One is based on the conventional clean fog pollution test. The other is a non-uniform rain test. The effect of varying the parameters of the rain test on bushing performance has been measured. Five different variants of the rain test have been used. The performance of a conventional bushing has been found to be much inferior to that of a hollow porcelain shell. Vario

G674: Characterization of Nox In Utility Flue Gases: Study

A study to evaluate NOx and N20 emissions from 11 electric utility boilers in Canada has been conducted by Energy and Environmental Research Corporation (EER) under contract with the Canadian Electrical Association (CEA). This study included 02, C0, C02, N0x and N20 measurements and fuel analyses for each of the plants. Results for N0x and N20 emissions are related to various operating parameters, and compared to U.S. EPA emission factors for N0x (and C0) emissions. Boilers which were tested inc

U419: Utility-Connected Wind Turbine Generator

This report details the results of 12 months of monitoring a wind turbine generator operating interconnected with a utility distribution system. The various technologies and instrumentation used in monitoring are described, the results examined and conclusions drawn. Although the project was primarily designed to observe the electrical and mechanical integrity, effectiveness, performance and compatibility with a utility distribution system, of the wind turbine generator, an examination of cost e
