Aims

•       The aim of this module is to provide students with an understanding of high voltage engineering, phenomena and technology and to introduce basic high voltage generation and measurement techniques.
•       The course is designed to be of value to engineers whose task is the planning and operation of an electricity supply system.

Outline Of Syllabus

•       High voltage breakdown mechanisms: Withstand levels and S curves; coordination of insulation; high voltage breakdown mechanisms in solids, liquids, gases and in a vacuum.
•       Partial Discharge: Insulation resistance, tan 'delta', partial discharge measurements; Non-destructive testing of apparatus.
•       Switchgear: Switchgear types; principles of operation; arcs; interruptions switching phenomena; standards.
•       HV testing: Production of HV test voltages; impulse generators; measurement of high voltages.
•       System overvoltage: Power frequency and harmonic overvoltage, switching and lightning overvoltage; overvoltage protection devices.
•       Introduction to DC Power Transmission Technology, including recent technological trends.
Comparison of AC and DC transmission systems, multi-terminal DC systems
•       Introduction to FACTS (Flexible Alternating Current Transmission System ) devices

Learning Outcomes

Intended Knowledge Outcomes

On successful completion of the module the student will be able to:

•       Know the principles behind the HV breakdown mechanisms in solids, liquids, gases and in a vacuum, and discuss dielectric breakdown of HV elements.
•       Explain what partial discharge is and how to measure partial discharge activity.
•       Describe the way of design and develop HV AC and DC voltages and currents
•       Demonstrate how to do HV testing for HV equipment.
•       Appreciate the techniques used to generate and apply measuring HV test voltages of impulse, dc and ac high voltages.
•       Appreciate the sources of HV Transient over voltages in the electricity network.
•       Analyse the different types of HV Switchgear and their principles of operation.

Intended Skill Outcomes

On successful completion of the module the student will be able to:

•       Use calculations, evaluation and problem solving skills relevant to HV engineering.
•       Develop skills in researching relevant information and be able to summarise information from relevant sources and draw conclusions from that information.
•       Demonstrate a critical understanding of the relevant theoretical concepts for HV breakdown.
•       Identify problems, produce and appraise solutions to breakdown of HV power system elements.
