Summary of Content

This module examines the design, commissioning and testing of high voltage plant and insulation systems and aims to develop in the student an understanding of the stresses which components and sub-systems are subject to in service and how these stresses can cause degradation and ultimate breakdown in the plant. The student will apply this understanding to the analysis of individual items of plant to determine the likely stresses prevalent, the consequences and the design features which should be incorporated to alleviate the problems. The student will apply the knowledge gained to evaluate when a condition monitoring policy should be adopted and how this should be realized

Syllabus

The teaching syllabus will cover the following areas: HV Systems : Overview ofHV plant, insulation systems, insulation system coordination, the design, commissioning and testing of HV systems Stress Conditions : In-service stress conditions for a variety of plant and systems, including electrical, mechanical, thermal and environmental stressing for motors, generators, transformers, cables, overhead lines, outdoor insulators and circuit breakers. Evaluation of Stresses and performance : Methodology for the evaluation of the likely stresses on a given item of plant. Design features to accommodate/alleviate such stresses. Evaluation of performance. Condition Monitoring Strategy : Reliability and its assessment for both individual items of plant and sub-systems, financial loss through loss of output and repair/replacement costs, different approaches to the aging problems. Measurable Phenomena : Measurable phenomena associated with degradation/normal operation. This will include the emission of light, heat, sound, electromagnetic radiation, physical/chemical changes for a variety of power plant items. Measurement Technology : Measurement instrumentation/transducers available to characterize degradation phenomena. This will include both generic forms of instrumentation for particular types of phenomena and specific, commercially available instruments, their advantages, disadvantages and limitations. Measurement Strategy : Single vs multi-parameter measurements and computer control/advanced signal processing techniques vs simple manual measurements, advantages, disadvantages and limitations.

Learning Outcomes

On completion of this module the student should be able to:1. Outline the process of design, commissioning and testing of HV plant and the mechanisms which stress power plant and systems under typical in-service conditions.(AM1,AM3,AM5)2. Evaluate, for a given condition, the likely/possible stresses on a given item of plant or system and application of outcome to the design of power plant components and sub-systems. (AM1)3. Determine, for a given situation, the advantages and disadvantages of adopting a condition monitoring policy and the appropriate measurable phenomena to be adopted (AM1, AM7)4. Evaluate for a given condition monitoring strategy, the specific instrumentation to be used and the associated measurement strategy (AM1)

Teaching / Learning Strategy

The main teaching method will be based on lectures with industrial visits to relate theoretical concepts to practical experience. The students will be expected to perform directed reading exercises and self-learning exercises on topics related to High Voltage and Condition Monitoring. Tutorials will be used to reinforce the module material and to discuss the issues raised by the directed reading.
