Which of the following represents a distribution layout pattern?

The grid layout is a common distribution pattern in utility distribution systems. This pattern is characterized by a network of interconnected lines that provide redundancy and multiple paths for electricity flow. By employing a grid layout, utilities can enhance reliability and flexibility in power distribution. If one path is down due to maintenance or fault, electricity can still be rerouted through other lines, ensuring that service remains uninterrupted for users.

In contrast, other patterns like a circular layout typically offer less flexibility and can present challenges in servicing and maintaining the network. Random layouts lack the systematic organization necessary for efficient distribution and may lead to difficulties in managing power flow and outages. A cluster layout, while it can be effective in some contexts, does not generally provide the redundancy and robustness that grid layouts offer. Thus, the grid layout is favored for its efficiency and reliability in meeting the demands of a distribution system.
