LaboratoryHigh Voltage Laboratory

The University of Canterbury High Voltage Laboratory is a specialist facility for the testing, measurement and research of high-voltage electrical equipment, insulation systems and power engineering components. The laboratory supports applied research, teaching, standards-based testing, failure investigation and industry consulting across a wide range of high-voltage and power-system applications. The laboratory includes major high-voltage test infrastructure for AC withstand testing, impulse voltage testing, partial discharge measurement, dielectric diagnostics, transformer and substation equipment assessment, and controlled power-frequency testing. Test capabilities include power-frequency AC testing up to 400 kV, impulse voltage testing up to 1400 kV, partial discharge measurement and analysis, transformer diagnostic testing, tan delta / power factor testing, and specialist measurements for high-voltage insulation systems. The facility is used to investigate the performance, condition and failure mechanisms of electrical insulation and high-voltage apparatus. Typical test objects include transformers, bushings, insulators, cables, switchgear, instrument transformers, surge arresters, rotating machine insulation, dielectric materials and prototype high-voltage components. The laboratory supports collaborative work with industry, researchers and students, including equipment condition assessment, product testing, forensic failure investigation, insulation ageing studies, high-voltage measurement development, and the evaluation of emerging technologies for power systems and electrification.
