⚡ High-Voltage Test Area
The High-Voltage Laboratory of the Mona Ghassemi Research Group at The University of Texas at Dallas includes a dedicated area specifically designed for conducting high-voltage experiments. As is standard practice in high-voltage laboratories, this test area is enclosed by a grounded, mesh-type safety enclosure to ensure personnel protection during operation.
The enclosure serves to physically isolate the test zone, restrict unauthorized access while experiments are in progress, and maintain appropriate electrical clearance distances. All metallic components of the enclosure are properly bonded to the laboratory grounding system, providing a low-impedance path for fault currents and minimizing touch and step potential hazards. This design enables safe, controlled, and repeatable execution of high-voltage testing in accordance with established laboratory safety practices.

The ADP300C vacuum drying oven enables controlled vacuum drying through direct heating in a decompressed chamber, supporting moisture removal and material conditioning for high-voltage insulation applications.
A 17.3-gallon acrylic vacuum chamber (16 × 16 × 16 in. internal volume), manufactured by Sanatron Inc., is used to provide a controlled low-pressure environment for high-voltage and insulation studies. The chamber is rated to 0.075 Torr, features dual-scale pressure monitoring, and includes dedicated pump and venting valves. High-voltage feedthroughs rated up to 20 kV enable electrical testing under vacuum conditions. The system is evacuated using a 0.25-hp vacuum pump capable of reaching 5 Pa, ensuring reliable and repeatable low-pressure operation.
