Examples of Projects Steel Dynamics Electrical Engineering Interns Have Completed

• Support substation reliability by inspecting and documenting current conditions of PTs (Potential Transformers) and CTs (Current Transformers), preparing inventories of available spares, and identifying components that require ordering for contingency planning.
• Assist with preventative maintenance of high-voltage substations, including reading equipment nameplates, assessing transformer health, and developing documentation based on OEM specifications and site safety standards.
• Collaborate with engineering teams to optimize safety practices by applying arc flash labels, observing lockout/tagout procedures, and reinforcing “trust but verify” principles when interpreting electrical schematics and prints.
• Participate in substation upgrade projects by tracing wire diagrams, creating custom wire labels, updating schematics, and loosely managing documentation for labeling systems across GE and TMEIC controls.
• Contribute to instrumentation and control design by programming HMIs such as C-more for real-time temperature displays and developing logic in Studio 5000 to automate screen changes for furnace monitoring systems.
• Assist in troubleshooting and rebuilding damaged electrical systems, including camera systems like UNILUX used for surface inspection, and sourcing replacement components for system restoration.
• Verify and correct electrical blueprints for major furnace systems (e.g., Round-Top-Melter, Tilter-Holder-Furnace), documenting any discrepancies and updating plans to improve installation accuracy and efficiency.
• Perform electrical inventory management by cataloging leftover materials from previous installations, preparing bill of materials for upcoming commissioning projects, and supporting procurement planning.
• Gain hands-on experience with field installations and maintenance tasks by shadowing electricians during troubleshooting, learning conduit work, motor disassembly, wiring practices, and electrical safety standards in live industrial environments.
• Support cross-functional communication by coordinating with contractors, vendors, and internal departments on projects involving trailer power feeds, radiation detector values, and cold mill upgrades, while learning foundational concepts in power distribution and teamwork.
