Let's analyze the question and the diagram step by step: ### Step 1: Understand the Question The question is asking **what type of network configuration** is shown in the diagram on the right side. It gives two options: - Open point - Distribution substation ### Step 2: Analyze the Diagram - The diagram depicts a distribution network. - There are several vertical lines connected to a main horizontal line (bus). - The vertical lines are interconnected at the bottom and middle, with two open switches (represented by the diagonal lines through circles). ### Step 3: Identify Key Features - The network forms a loop at the bottom, but the switches are open. - **"Open point"** refers to a configuration where a looped network is operated with one or more open switches, making it function as a radial network for operational simplicity and protection coordination. ### Step 4: Distribution Substation - A **distribution substation** is a facility where voltage is transformed and distributed but doesn't describe the network configuration. ### Step 5: Conclusion - The diagram clearly shows a loop with open points (open switches), which matches the "open point" network configuration. --- ## **Final Answer:** **The type of network configuration for the shown diagram is:** ### **Open point** **Explanation:** The diagram shows a ring main or loop network with switches kept open at certain points, which is characteristic of an "open point" configuration. This is done to ensure the network operates radially but can be quickly restored from the other side in case of a fault.
