Easergy T300

A powerful Remote Terminal Unit (RTU) for Feeder automation

Part of PowerLogic

Remote control and monitoring for Energy distribution automation

Easergy T300
  • Features

    The new benchmark in power distribution 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.
    Flexible communication to control centres and wider networks

    • Standard and more secure protocols: IEC 101/104, DNP3, IEC 61850, Modbus
    • Open peer-to-peer communication for self-healing applications
    • Flexible communication media: Ethernet, USB, GPRS, 2G, 3G, 4G, RS232/485...
    • Open to third party devices with many protocol capabilities
    • Wi-Fi connectivity for local operation  
    Strengthen cyber security management 

    • Compliance with IEC 62351 and IEEE P1686
    • SCADA communication security and Wi-Fi access
    • Local and remote access control based on RBAC
    • Connection security for maintenance (local and remote): HTTPS, SSH
    • Protocol security for file transfer: SFTP  
    Medium Voltage network management 

    • Advanced fault current detection for networks with distributed generation
    • MV voltage monitoring and broken conductor detection
    • Flexible centralized or decentralized automation (FDIR) system with IEC 61131 software PLC
    • LV Power measurement according to IEC 61557-12
    • LV Power quality according IEC 61000-4-30 Class S
    • Manages up to 24 Load Break Switches 
    Transformer, Medium Voltage and Low Voltage network monitoring
    • LV broken conductor detection
    • LV Power measurement according to IEC 61557-12
    • LV Power quality according IEC 61000-4-30 Class S
    • Transformer temperature monitoring  
    Backup power supply range for control and monitor application

    The Easergy T300 back-up power supply is designed for power interruptions in order to maintain control and monitoring of the MV substation during the outage. 

    Remote and local maintenance with simple tools

    • Embedded web server compatible with PC, Smartphone and tablet computers
    • Remote communication network, local ETH or Wi-Fi access
    • Firmware and remote/local database update security
    • Full Web applications for substation and RTU asset management
    • Simple configuration update on site, due to modular construction


     Easergy T300 enables you to:

    • Reduce MV and LV outage durations (SAIDI)
    • Manage Voltage regulation with accuracy
    • Synchronize voltage measurement on the feeder in order to facilitate distributed generation integration
    • Measure the MV and LV power quality according to EN50160
    • Manage MV and LV energy growth (peak shaving)
    • Reduce technical and non-technical losses
    • Reduce capex due to a single multi-application, modular offer
    • Reduce installation, operation and maintenance costs
    • Manage better your Network and substation assets


    Easergy T300 is dedicated to Medium Voltage and Low Voltage public distribution network management.
    Typical applications include:

    • Underground MV/MV and MV/LV Substation Control and Monitoring
    • Overhead Load Break Switch (LBS) Control
    • Overhead Transformer and MV/LV Network Monitoring
    • Pad-mounted Transformer and MV/LV Network Monitoring
    • MV Line and End-of-line Monitoring
    • Overhead Capacitor Bank Control
    • LV Network Distribution Monitoring
    • Distributed Energy Resources Control and Monitoring
