Easergy T300

A powerful Remote Terminal Unit for feeder automation

Part of PowerLogic

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 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
    Easergy HU250 - Head unit communication gatewayEasergy SC150 - MV switchgear controllerEasergy LV150 - Transformer and LV switchboard monitoringEasergy PS100/PS50/PS25 - Wide range of backup power suppliesFlexible communication to control centers and wider networks
    Master and slave protocols: IEC 60870-5-101/104, DNP3, Modbus, IEC 61850Multi-protocol and redundancy managementPeer-to-peer communication for self-healing applicationsFlexible communication media: Ethernet, USB, 2G, 3G, 4G, RS232/485Wi-Fi connectivity for local operationStronger cybersecurity management 
    Compliant with IEC 62351 and IEEE P1686SCADA communication security (IEC 62351-5)Local and remote access security based on RBAC (IEC 62351-8)Connection security for maintenance (local and remote): HTTPS, SSHProtocol security for file transfer: SFTPAuthentication by centralized Radius clientMedium voltage network management 
    Advanced non-directional and directional fault current detection for all neutral systems MV broken conductor detection based on voltageAutomation: Sectionalizer; Auto transfer source; Self-healing and dedicated, based on IEC 61131-3 PLCMV Power measurement according to IEC 61557-12MV Power quality according to IEC 61000-4-30 Class SCapable of managing up to 24 Load Break SwitchesTransformer and low voltage network monitoring
    LV broken conductor detection (fuse detection)LV Power measurement according to IEC 61557-12LV Power quality according IEC 61000-4-30 Class STransformer temperature monitoringBackup 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.
