Intern, Medium Voltage Test Engineering

The role

You will build and operate high-voltage test infrastructure to characterize and qualify insulation systems in medium-voltage power electronics. This includes test bench setup, dielectric characterization campaigns, degradation analysis, and failure mode documentation.

What you will do

• Design, build, and operate medium-voltage test benches
• Own bench system design including HV clearances and grounding architecture
• Build and document test fixtures for cable assemblies, busbars, and insulation specimens
• Learn and strictly enforce MV lab safety protocols
• Execute dielectric strength tests and own data collection and reporting
• Perform insulation resistance, polarization index, and dielectric loss measurements
• Run partial discharge measurements end to end
• Execute accelerated aging and environmental stress campaigns
• Track and analyze degradation trends across test campaigns
• Build structured data workflows and visualizations

Required qualifications

• Pursuing a BS or MS in Electrical Engineering, Physics, or Materials Science
• Coursework in electromagnetics, dielectrics, or high-voltage engineering—or demonstrated independent study in this area
• Genuine technical interest in high-voltage physics, insulation behavior, and failure mechanisms
• Strong debugging instincts: ability to isolate failure modes, design targeted experiments, and close findings into documented root causes
• Detail-oriented and safety-conscious

Nice to have

• Exposure to partial discharge theory, dielectric spectroscopy, or high-voltage lab techniques
• Familiarity with IEC or IEEE dielectric testing standards (IEC 60243, IEC 60270, or similar)
• Experience with data analysis and visualization in Python or MATLAB
• Prior lab research in materials characterization, high-voltage systems, or power electronics
