Distribution Feeders and Lines
How local circuits carry electricity from substations toward customers.
Electrical safety boundary: this page explains the system conceptually. It does not provide procedures for live electrical work, switching, protection settings, conductor/breaker sizing, substation access or high-voltage operation. Those activities require qualified professionals, applicable codes and utility procedures.
Where this fits
How local circuits carry electricity from substations toward customers.
Core system ideas
Feeders branch through neighbourhoods, commercial areas and industrial zones.
Voltage drop, thermal limits, protection coordination and physical condition constrain how much load a feeder can serve.
Actual line design and electrical work require qualified utility engineers and applicable codes.
Interfaces and tradeoffs
Distribution connects the bulk system to millions of individual loads and increasingly to distributed generation and storage. Local voltage, feeder capacity and asset condition matter as much as system-wide energy supply.
What organizations measure
Peak loading, voltage, losses, interruptions and condition.
