Electrical and Computer Engineering facilities
The College of Engineering has some of the best-equipped research and teaching laboratories in New Zealand.
The Communications Laboratory is primarily engaged in research into advanced digital wireless systems. The work encompasses theoretical, simulation and DSP-based hardware prototyping and the projects underway include:
- Development of advanced adaptive receiver structures for fading dispersive channels. This includes work on near optimum, reduced complexity receivers.
- Various studies of advanced coded modulation systems for use in the wireless environment.
- The development, including a hardware prototype, of adaptive wireless systems to allow the experimental study of array performance and the investigation of multiuser detection and decoding algorithms.
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.

The Power Research Lab (situated alongside the Power Electronics Lab) is a postgraduate research laboratory specialising in higher power applications. Here you will find projects and equipment associated with renewable and sustainable energy electrical systems, electric vehicles and utility power quality.
The Department of Electrical & Computer Engineering has an extensively equipped Optics Laboratory located on the 2nd Floor of the ECE Link block. This Laboratory is managed by Dr. Steve Weddell and is unique in that it specialises in Adaptive Optics (AO) research.
Specialised equipment includes an optical table, spatial light modulator, a bimorph mirror, 4 computers and various optical assemblies, including both gas and semiconductor 3B and 3R class lasers and several high-speed CCD and CMOS cameras. Safety equipment, such as special glasses and emergency lighting, in addition to signage warning that laser-based experiments are conducted within the facility, are clearly shown over the front door to the lab and in strategic areas within the laboratory. New users are given personal instruction by the laboratory manager, and this is supplemented with course notes in the safe use of lasers before they are allowed to use any equipment.
Currently, the Optics Lab is being used to configure adaptive optics experiments, specifically, wavefront sensors, for on-sky testing, and to confirm simulated results. The laboratory may be used for either astronomical and ophthalmological applications, or as mentioned, for measuring LED lighting emissions.
This laboratory is used for many undergraduate courses for laboratory experiments and projects. It contains 28 workbenches, each equipped with a PC, a dual-channel 100 MHz oscilloscope, a DC power supply, multimeters and a multipurpose waveform generator. Each bench can seat up to three students.
A wide range of specialised instrumentation is also kept in this laboratory to support final year projects and research conducted by staff and postgraduate students. Some of the specialised equipment includes: RF and microwave spectrum analysers, a microwave vector network analyser, microwave power meter, RF and microwave signal sources and pulse generators.
Most academic staff teach in this laboratory.
The Machines Laboratory is one of the main teaching laboratories in the department. It is used for First and Second Professional Year laboratories as well as Third Professional Year Projects and postgraduate projects.
It is used for the undergraduate teaching of:
- Fundamentals of Electrical Engineering
- AC Machines
- DC Machines
- Power Electronics
The Control Laboratory is used for the teaching of the Control Systems 1 and Control Systems 2 courses within the department. In addition it is used to house a number of third professional projects each year.
Information on the Digital Systems Technical Library relates to digital systems, development tools, PCB design and soldering.
The Power Electronics Lab (situated alongside the Power Research Lab) is used for some undergraduate labs (involving solar-electric cars and electric go-kart speed control) and for postgraduate research specialising in the fast growing field of power electronics. This field is very wide, ranging from small power supplies of just a few watts (as you would find in a smartphone) to high voltage static convertors (1.2GW). Power electronics is critical for the efficient distribution and use of electric power and as such plays a key role in reducing the environmental impact of electric energy use.
