Easergy T300

A powerful Remote Terminal Unit for feeder automation

Remote control and monitoring for energy distribution automation

Easergy T300
  • Features

    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 Transfert Switch 
    • Volt/VAR optimization support for distributed generation integration 
    • MV and LV power and quality measurement according to standard EN 50160 
    • Asset management efficiency
    Modular offer description by function

    • Easergy HU250 - Head unit communication gateway 
    • Easergy SC150 - MV switchgear controller 
    • Easergy LV150 - Transformer and LV switchboard monitoring 
    • Easergy PS100/PS50/PS25 - Wide range of backup power supplies
    Flexible communication to control centers and wider networks

    • Master and slave protocols: IEC 60870-5-101/104, DNP3, Modbus, IEC 61850 
    • Multi-protocol and redundancy management 
    • Peer-to-peer communication for self-healing applications 
    • Flexible communication media: Ethernet, USB, 2G, 3G, 4G, RS232/485 
    • Wi-Fi connectivity for local operation
    Stronger cybersecurity management 

    • Compliant with IEC 62351 and IEEE P1686 
    • SCADA communication security (IEC 62351-5) 
    • Local and remote access security based on RBAC (IEC 62351-8) 
    • Connection security for maintenance (local and remote): HTTPS, SSH 
    • Protocol security for file transfer: SFTP 
    • Authentication by centralized Radius client
    Medium voltage network management 

    • Advanced non-directional and directional fault current detection for all neutral systems  
    • MV broken conductor detection based on voltage 
    • Automation: Sectionalizer; Auto transfer source; Self-healing and dedicated, based on IEC 61131-3 PLC 
    • MV Power measurement according to IEC 61557-12 
    • MV Power quality according to IEC 61000-4-30 Class S 
    • Capable of managing up to 24 Load Break Switches
    Transformer and low voltage network monitoring

    • LV broken conductor detection (fuse 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 monitoring applications

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

    Remote and local maintenance with simple tools

    • 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


    Benefits

    • Reduce MV and LV outage durations (SAIDI) 
    • Manage voltage regulations with accuracy 
    • Synchronize voltage measurements on the feeder in order to facilitate distributed generation integration 
    • Measure the MV and LV power quality according to EN 50160 
    • Manage MV and LV energy growth (peak shaving) 
    • Reduce technical and non-technical losses Reduce CAPEX with a single, multi-application, modular offer 
    • Optimize asset management and the equipment lifespan

    Applications
