Laboratory Capabilities

The Paul B. Jacob High Voltage Laboratory serves as an independent, non-industrial, university center for high voltage engineering. The laboratory was constructed as part of the Simrall Electrical Engineering Building in 1977 and has been supporting the development of high voltage education and industry ever since.

The main laboratory hall has a floor area of 33.5 x 24.5 m and a minimum ceiling height of 15.2 m making it the largest high voltage laboratory among North American universities. The main laboratory is equipped with a 5 ton crane, full-scale wet test rack, faraday cage, and grounding mesh. As an independent laboratory, test results are held in the strictest confidence. In addition to the main high voltage laboratory, our smaller laboratory enables the performance of long duration evaluations at lower voltages (under 200 kV).


The main equipment in the laboratory:

  • 3000 kV (56 kJ) impulse generator
  • 1000 kV (1 MVA) 60 Hz transformer
  • 400 kV DC supply
  • 250 kV 60 Hz transformer
  • 400 kV portable impulse generator
  • 400/200/100 kV multi test set (impulse/DC/AC)
  • Programmable surge generator (EMC)
  • Multiple dielectric test sets
  • Climate chamber (-73°C ... +175 °C, 27 cubic ft workspace)
  • Porosity test setup (max. 5000 psi)
  • Custom accelerated ageing chamber
  • 3 tracking and erosion systems (RWDT)
  • Standard wet test facility

Measurement Devices

In addition to standard measurement and data acquisition units, the laboratory can record:

  • Radio Interference Voltage (RIV)
  • Partial Discharge (PD)
  • Corona (night vision camera)
  • Capacitance and Dissipartion Factor

Evaluations are performed according to national and international standards as well as customer specifications.

Tracking and Erosion

The high voltage laboratory has constructed 3 tracking and erosion (RWDT) test setups.
