The High Voltage Laboratory is a graduate research and undergraduate teaching laboratory. It specialises in the measurement and testing of equipment and components of Electric Power Engineering.
Equipment in the laboratory
The High Voltage Laboratory testing facilities are based around two major pieces of equipment, namely an impulse generator and a HVac testing transformer. These allow controlled testing of equipment and material insulation, such as under dry and wet conditions. While testing can be undertaken according to standards requirements, staff specialize in developing testing requirements for specific customer requirements and more explorative research.
Research is geared towards understanding the electric field and high voltage phenomena, developing innovative equipment for the electrical industry and new technologies which use high voltage concepts in their design.
Teaching laboratories include studying the breakdown of air under varying atmospheric conditions, especially moisture, varying supply voltage and frequency and under multiple insulation arrangements. They are particularly geared towards the use of live-line techniques for transmission and distribution system maintenance. Transformer insulation condition measurement is also a set laboratory exercise.
Lectures in high voltage are embodied into specific courses associated with Electrical Engineering.
In electrotechnology, electric fields, insulation materials and the physics of the breakdown of gases, liquids and solids is presented, along with applications from micro-electronics to power engineering. A practical laboratory exercise involves studying the breakdown of air under varying atmospheric conditions, especially moisture, varying supply voltage and frequency and under multiple insulation arrangements. They are particularly geared towards the use of live-line techniques for transmission and distribution system maintenance.
In power systems engineering, various methods of measuring the breakdown of insulation are presented. The equipment required to undertake these tests and the apparatus required to measure insulation characteristics is also presented. The laboratory exercise involves the measurement of transformer insulation condition using a high voltage capacitance and dissipation factor test set.
