Download Optical Temperature Monitoring of Electrical Power Transformer Networks Book in PDF, ePub and Kindle
This thesis presents an optical sensor network model designed to monitor temperature of transformers at multiple substations from one central location. Fiber Bragg Grating (FBG) has been used as the optical sensing element for transformer temperature monitoring. Suitable FBG parameters and specifications have been investigated and modeled that fit best for this application. Optical sensor network is laid on top of the transmission line network. This reduced the cost of fiber installation. The wavelengths of backscattered light at different temperatures for the modeled Fiber Bragg Grating have been obtained. These values are used as a reference to find the actual temperature of the transformers from the central station. Different network topologies that can be implemented for such applications are presented and the most suitable one is assessed for link budget and cost analysis of the optical sensor network. The temperature sensing range is from 30°C to 90°C. The minimum temperature accuracy that can be achieved is about 0.010C. Time Division Multiplexing (TDM) is employed to identify individual transformers in the network at the central station. A Model to find an optimal node to place the optical sources is also presented. The temperature monitoring of standard IEEE transmission networks has been obtained.

Download Optical Fiber Sensor Technology Book in PDF, ePub and Kindle
Environmental and chemical sensors in optical fiber sensor technology The nature of the environment in which we live and work, and the precarious state of many aspects of the natural environment, has been a major lesson for scientists over the last few decades. Public awareness of the issues involved is high, and often coupled with a scepticism of the ability of the scientist and engineer to provide an adequate, or even rapid solution to the preservation of the environment before further damage is done, and to achieve this with a mini mum of expenditure. Monitoring of the various aspects of the environment, whether it be external or internal to ourselves and involving chemical, physical or biomedical parameters is an essential process for the well-being of mankind and of the individual. Legis lative requirements set new standards for measurement and control all around us, which must be met by the most appropriate of the technologies available, commensurate with the costs involved. Optical fiber sensor technology has a major part to play in this process, both to complement existing technologies and to promote new solutions to difficult measurement issues. The developments in new sources and detectors covering wider ranges of the electromagnetic spectrum, with higher sensitivity, allow the use of techniques that some time ago would have been considered inappropriate or lacking in sufficient sensitivity.

Download Recent Trends in the Condition Monitoring of Transformers Book in PDF, ePub and Kindle
Recent Trends in the Condition Monitoring of Transformers reflects the current interest in replacing traditional techniques used in power transformer condition monitoring with non-invasive measures such as polarization/depolarization current measurement, recovery voltage measurement, frequency domain spectroscopy and frequency response analysis. The book stresses the importance of scrutinizing the condition of transformer insulation which may fail under present day conditions of intensive use with the resulting degradation of dielectric properties causing functional failure of the transformer. The text shows the reader how to overcome the key challenges facing today’s maintenance policies, namely: The selection of appropriate techniques for dealing with each type of failure process accounting for the needs of plant owners, plant users and wider society; and Cost-efficiency and durability of effect. Many of the failure-management methods presented rely on the fact that most failures give warning when they are imminent. These potential failures give rise to identifiable physical conditions and the novel approaches described detect them so that action can be taken to avoid degeneration into full-blown functional failure. This “on-condition” maintenance means that equipment can be left in service as long as a specified set of performance standards continue to be met, avoiding the costly downtime imposed by routine and perhaps unnecessary maintenance but without risking equally expensive failure. Recent Trends in the Condition Monitoring of Transformers will be of considerable interest to both academic researchers in power systems and to engineers working in the power generation and distribution industry showing how new and more efficient methods of fault diagnosis and condition management can increase transformer efficiency and cut costs.
