Which component connects the substation to the area where power is to be distributed?
Distributors
Service mains
Feeders
All of these
Feeders
Feeders are conductors of high current-carrying capacity that connect the substation to the distribution area. They are specifically designed to carry bulk power without having any intermediate tappings, ensuring voltage drops remain within permissible limits along the transmission path.

The electrical distribution network is hierarchy-based. The Feeder acts as the primary link between the substation (source) and the Distribution Transformer or the beginning of a Distributor. Since Feeders have no consumer tappings, their current is assumed to be constant throughout their length, simplifying the calculation of voltage regulation.
Feeders carry power from the substation to the distribution transformer with no tappings.
Distributors are conductors from which tappings are taken for consumers.
Service mains connect the distributor to the consumer's terminals.
Design of feeders is primarily based on current-carrying capacity.
Design of distributors is primarily based on voltage drop limitations.
Efficient transmission of bulk power from substation
Minimized voltage fluctuations at the start of the distribution network
High cost due to large conductor cross-section
Not suitable for direct consumer connection
Connecting Substations to Distribution Transformers
High-voltage distribution backbone systems
Option A (Distributors) are lines where consumers connect. Option B (Service mains) are the final links to residential or commercial meters. The Feeder is exclusively the 'trunk' line from the substation.
Voltage regulation is the critical design constraint for feeders.
C is correct тАФ Feeders serve as the dedicated link between the substation and the distribution network without any intermediate tapping.
In competitive exams, remember the mnemonic 'F-D-S': Feeders (no taps) -> Distributors (taps taken) -> Service Mains (final drop to load).
