Decentralized DTU

Decentralized Distributed Terminal Unit is a new-generation, microprocessor-based station terminal unit integrating telemetry, status indication, remote control, energy metering, protection, and communication functions. It consists of a common unit and multiple bay units. Designed for multi-feeder centralized monitoring applications in distribution rooms, ring main units (RMUs), and switching stations, it works with communication systems to form various ring and radial distribution automation networks. This enables distribution automation functions such as real-time monitoring of distribution line status, fault detection, fault isolation, and restoration of power to non-faulted sections.
