his unit will cover the following topics:

Power system plant:

• Overhead line (Basic constructional details, illustration of electrical clearances, discussion of thermal ratings)
• Cables (Basic construction of single core cables, electrical parameters of cables, thermal modelling)
• Switchgear (Types of switchgear, arc model, high and low resistance interruption techniques, description of transient recovery voltages)
• Transformers (Transformer structure and functions of basic components including oil/cellulose insulation materials, magnetic circuit and volts per turn calculation, phasor connections / parallel operation / impedance selection)

High voltage testing techniques and insulation design of power system plant (including a laboratory class)

Protection of power systems

• Earth-fault calculation for a power system, basic principles of power system protections, Numerical solution of an overcurrent protection and coordination scheme for protecting a typical power network.

The course unit aims to:

• Introduce the fundamental issues relating to the design of high voltage power system plant
• Introduce the use of high voltage testing within a laboratory environment 
• Explore the protection of power systems.

On successful completion of the course, a student will be able to:

ILO 1: Compare the methods used for HV testing of power system equipment

ILO 2: Appraise the design of an item of power system plant and determine whether it is fit for purpose

ILO 3: Describe the fundamental design principles of the four major items of power system plant (cables, lines, transformers and switchgear)

ILO 4: Analyse the design of a simple protection scheme and assess if it is fit for purpose

ILO 5: Explain the basic design of simple power system protection schemes

This course is delivered through face to face lectures that involve problem classes during the sessions. Additional material including films and worksheets are provided in the virtual learning environment. Students are encouraged to ask questions during the classes and use is made of sli.do to capture these.

The course also involves demonstrations within the high voltage laboratories where students see practical testing being carried out on power system equipment.
