According to Dr. A.A. Abdelmalik, Materials Physics Research Group Leader, the High Voltage Laboratory and the other laboratories in the Materials Science Laboratories are equipped to perform full-scale high voltage testing and study of different HV phenomenon. Among other state-of-the-art facilities, Glassman 400 kV HVDC Generator was recently installed in the Materials Science Laboratory of the Department of Physics targeting broad areas of research.
Dr. Abdelmalik further revealed that the 5 kV AC source, 35 kV DC source and the newly installed 400 kV DC Generator could be used for full-scale testing. “Programmable LCR bridge for capacitance and tangent delta measurements, picoammeter for time-domain dielectric analysis, high-tech oscilloscope, vacuum oven, and Brookfield digital viscometer,” he said; adding: “furthermore, we are in the process of acquiring special devices for partial discharge measurement, Karl Fischer moisture analyzer and Portable DGA Analyzer for transformer oil.”
While also commenting on the development, a member of the Research Group, Dr. A.A. Khaleed, said the group’s doors are not open only to advanced (PhD) researchers, but inquirers at the Masters level can also join the group and learn as well as contribute – just as undergraduate students are also welcome to make optimal use of the laboratories under guided supervision.
“These facilities are essential for both science and engineering students especially those interested in High Voltage engineering, which is basically experimental based. We are open for collaborations from within and outside the University”, he said.

Earlier, Dr. Abdelmalik explained that getting the Glassman 400 kV equipment started way back during his post doctoral work at Leicester University in ther UK.“I used the facility in Leicester; but somewhere along the line they got newer facilities and in trying to figure out how best to let go of it, I was contacted and asked whether I'd like to have it and I said yes sure, it'll help my University (ABU Zaria) greatly... So we contacted our VC here and solicited for funding to ship the equipment to Nigeria and here now is it with us!”
While speaking on the challenges faced by the Research Group in carrying out their works, Dr. Abdelmalik pointed out that power supply is quite an issue because the lab usually experiences low voltage supply between the hours of 9am to about lunch time, which means they cannot use the equipment within those hours. He, therefore, appealed to the University Management to further come to their aid by facilitating improved power supply to the lab and surrounding offices.
The Group’s research activities at the moment are in six principal areas:
- Characterization of engineered materials for various industrial applications,
- Integrity testing of high voltage insulation system in power equipment,
- Electrical ageing, degradation, and breakdown in insulation system of power equipment,
- Measurement and study of partial discharges (PD) in power systems,
- Reliability studies of power equipment, and
- Synthesis of nano-dielectrics – i.e. dielectric materials made from nanoparticles.
