The scenario
A surface copper mine requires a 15 kV distribution system to power large electric shovels and drills.
What is in this drawing
Read the decisions behind it.
01
115 kV grid connection stepped down to 15 kV via a 20 MVA transformer.
02
15 kV main switchgear distributes power to multiple feeders.
03
Each large load (shovels, drills) is fed via dedicated circuit breakers with ground fault protection.
Used for planning and documenting mine power distribution systems, ensuring proper protection and load distribution for high-power mining equipment.
