High/Low voltage power balance,
Sizing of MV/LV switchboards, distribution panels, transformers, UPS, generators,
Selectivity & protection studies,
Short-circuit, voltage drop, earthing, lightning protection calculations,
Lighting design using Dialux / Relux.
Schematics & drawings:
Single-line diagrams and synoptic diagrams,
HV/LV distribution schemes,
Cable schedules and lists,
Routing plans and layout drawings.
Coordinate interfaces with:
Battery process (coating, assembly, calendaring, etc.),
HVAC / utilities (power requirements, control),
Safety systems: fire detection (SSI), sprinklers, gas suppression,
PLCs, BMS / SCADA systems.
Integrate specific gigafactory constraints:
Very high continuous loads,
Sensitivity to power continuity,
High energy redundancy,
Critical environments: dry rooms.
Reviewing execution studies: calculation notes, schematics, technical documents.
Ensuring compliance with standards: NF C15-100, IEC, EN.
Handling RFI, technical discrepancies, and participation in design approvals.
On-site technical support:
Installation checks,
FAT/SAT for transformers, switchboards, UPS, etc.,
Testing and commissioning.
Writing: technical specifications (CCTP), calculation notes, design documents (APS/APD/EXE), datasheets.
Contributing to tenders and supplier selection.
Monitoring design schedules and reporting to the Electrical Lead.
Participation in multidisciplinary meetings and BIM reviews (Revit MEP).
Medium/Low Voltage: transformers, MV switchgear, main switchboards.
UPS, generators, redundancy.
Selectivity, protection, continuity of service.
Earthing, lightning protection.
Low Current Systems (CFA)
