Electrical Power & High Voltage (HV) Systems
Electrical power and high-voltage systems engineering covers the design, commissioning, and safe operation of medium- and high-voltage equipment — switchgear, transformers, cable systems, bus ducts, and protection relays — that supply and distribute power to battery production facilities and to the packs themselves during test. As a hard skill it requires power systems analysis (load flow, short-circuit, arc-flash per NFPA 70E), understanding of HV isolation and interlocking requirements, and the elevated PPE and safe-approach discipline mandated for work on energized equipment above 600 V. Electrical engineers apply this when engineering the MV distribution feeding a gigafactory's formation and testing areas, when sizing high-voltage DC bus systems for pack-level abuse testing, and when coordinating protection devices across a plant substation to achieve selective fault isolation without tripping production.
