LV systems: Power distribution panels, MCCs, UPS systems, DG systems
Power supply to semiconductor process tools and critical utilities

Perform:

Energization procedures and system start-up
Protection relay testing and coordination
Load testing and power quality analysis

Execute and review:

Commissioning procedures and electrical test scripts
FAT/SAT protocols
System validation and performance testing

System Integration

Ensure alignment between:

Electrical systems and process tool requirements
Facility infrastructure and critical power distribution
Automation systems (BMS, SCADA, MES interfaces)

Coordinate integration of backup power systems (UPS, DG) with critical fab loads
