Easergy T300
  • Features

    One modern solution to answer your evolving challenges and prepare your business for the future.

    Easergy T300 is a modular grid automation platform of hardware and firmware, and an application building block for medium voltage and low voltage 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 centers and wider networks
    • Standard and more secure protocols: DNP3, IEC 61850, Modbus, IEC 101/104
    • 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 extensive protocol library
    • Wi-Fi connectivity for secure 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 (Role Based Access Control)
    • 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 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 and fuse blown detection
    • LV power measurement according to IEC 61557-12
    • LV power quality according IEC 61000-4-30 Class S
    • Transformer temperature monitoring
    • Wireless and self powered LV feeder power meter measurement (IEC 61557-12)
    Back-up 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 PCs, smart phones, and tablets
    • 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 updates on site, thanks to modular construction


    Easergy T300 enables you to:
    • Reduce MV and LV outage duration (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, operational, and maintenance costs
    • Better manage 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 (DER) control and monitoring


    • Easergy T300 - Communicating power supply PS50
    • Easergy T300 - SC150 network management
