LHC main ring magnets cabling.
Primary distribution voltages range from 4 kV to 35 kV phase-to-phase 24 kV to 20 kV phase-to-neutral Only large consumers are fed directly from distribution voltages. Single-line diagrams SLD A single-line diagram shows the disposition of equipment in a substation or network in a simplified manner using internationally accepted symbols to represent various items of equipment such as transformers circuit breakers and disconnectors generally with a single line being used to represent three-phase connections. Relay wiring and automatism schematic diagrams.
Diagram of a possible configuration of ring final circuit.
High and low voltage distribution schematic diagrams. Most utility customers are connected to a transformer which reduces the distribution voltage to the low voltage utilization voltage supply voltage or mains voltage used by lighting and interior wiring systems.
