Easergy T300

The new benchmark in distribution network automation.

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 restoration
• Private network management (MV loops): Self-healing network management – Automatic Transfer Switch
• Volt/VAR optimization support for distributed generation integration
• MV and LV power and quality measurement according to standard EN 50160
• Asset management efficiency
