The scenario
An underground gold mine requires reliable 440V power distribution from a 11kV grid supply, with automatic transfer to a 500 kW diesel generator for critical loads during utility outages.
What is in this drawing
Read the decisions behind it.
01
11kV grid supply stepped down to 440V via 1 MVA transformer
02
500 kW generator integrated via ATS for critical bus
03
Critical loads (ventilation, pumping, lighting) connected to generator-backed bus
04
Non-critical load (conveyor) fed directly from main bus
Underground mining operations requiring continuous power for safety-critical systems, applicable to gold, copper, or coal mines with similar electrical infrastructure.
