The High Voltage Laboratory

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.

Research is geared towards understanding 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 Electric Power Engineering.

p-HV_Lab1.jpg (13505 bytes)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.
