Network Distribution refers to ...

• A. The network of customers in an area fed by a single transformer.
• B. A backbone connecting multiple substations.
• C. The network of customers in an area fed by several network transformers tied together with a grid of secondary cables.
• D. A closed loop delivering power to a single industrial facility.

Answer: (C)

Network distribution is the way power is delivered to many customers in a given area through an interconnected grid of secondary cables and multiple network transformers. This arrangement allows power to flow from more than one transformer and be re-routed if a component has a fault, which improves reliability for the customers fed from that area. The described choice captures this setup precisely: a network of customers in an area fed by several network transformers tied together with a grid of secondary cables.

The other descriptions don’t fit network distribution: a single transformer feeding an area is a radial arrangement with one main feed, not interconnected, so it lacks the multiple sources and cross-connections. A backbone linking multiple substations refers to the higher-level infrastructure that connects substations, not the local customer distribution network. A closed loop delivering power to a single industrial facility describes a loop serving one customer, not a network serving many.
