The distribution automation switch mentioned in the beginning provides advanced metering and automation capabilities for distribution circuits. This technology allows utilities to remotely monitor and control the distribution system, enabling faster fault detection, isolation, and restoration. It improves the reliability of the distribution system by reducing outage durations and improving overall system efficiency. to distribution occurs in a distribution substation, where the high-voltage power from the transmission grid is stepped down to a lower voltage suitable for distribution.
A loop distribution system has multiple paths for power flow, creating redundancy and improving reliability. Power can flow in multiple directions, allowing for alternative routes if there’s a fault or disruption in one section. Loop systems are often used in areas where reliability is critical, such as hospitals or data centers. A network distribution system is the most complex and provides the highest level of reliability. It consists of a network of interconnected feeders and transformers, forming a mesh-like structure. Power can flow through multiple paths, similar to a loop system, but with more interconnections.
Network systems are often found in urban areas with a high concentration of customers, as they offer greater flexibility for power restoration during outages. In the context of a university campus network, the distribution layer switches (DLs) extend the core network into individual buildings. Each building is connected to two core network locations for redundancy, ensuring network availability even if one connection fails. The DLs typically operate at 1 Gigabit per second (Gbps) speed, providing high-speed connectivity to the campus network for the building’s users and devices.
