CASE ANALYSIS
Scenario
A petrochemical refinery requires reliable power distribution with dual utility feeds and backup diesel generators. Power is stepped down from 11kV to 4.16kV for large motor loads and further to 480V for auxiliary services.
Key decisions
- Use of dual utility feeds with bus tie for redundancy
- Sizing of transformers (T1 and T2) for critical load handling
- Selective location of motor loads and reactive compensation on 4.16kV buses
When to reuse this
Suitable for brownfield plant expansions, critical process plants, and design of medium-voltage industrial distribution systems.
