Easergy T300 Remote Terminal Unit (RTU)is a modular platform of hardware and firmware, and an application building block for Medium Voltage and Low Voltage public distribution network management. It offers a single solution for control and monitoring from a simple pole-top device to a large MV/MV or MV/LV substation.
Easergy T300 RTU offers a wide range of functions to meet your needs, including:
Centralized and decentralized MV and LV distribution network management: fault location, isolation, and service restorationPrivate network management (MV loops): Self-healing network management – Automatic Transfer SwitchVolt/VAR optimization support for distributed generation integrationMV and LV power and quality measurement according to standard EN 50160Asset management efficiencyModular offer description by function
