TCA – MV Supervision & Automation RTUs

  • TCA-A: Directional Fault Passage Indicator (FPI) and switchgear monitoring for Overhead or Underground Distribution Grid. Medium Voltage Grid Monitoring for Distribution networks with FPI function.  Overhead or underground lines. Fault Location solution for semiautomated Distribution Networks through IEC 60870‑5‑104 communications. Suitable for a variety of grounding systems (solidly-grounded, impedance grounded, isolated or compensated-Petersen coil grounding).
  • TCA-C: RTU with built-in directional Fault Passage Indicator (FPI) for non-extensible 2-feeder and 3-feeder RMU. Cybersecure Monitoring and Automation solution for non-extensible Ring Main Units
    (RMU) in underground Distribution networks. Suitable for a variety of grounding systems (solidly-grounded, impedance grounded, isolated or compensated-Petersen coil grounding). It connects with SCADA and Control Centers systems using standard protocol IEC 60870‑5‑104, making FLISR solutions possible for Distribution System Operators (DSO).
  • TCA-D/E:  RTU with built-in directional Fault Passage Indicator (up to 5 FPI) for Overhead Load Break Switch and extensible switchgears. Distribution Monitoring and Automation solution
    for extensible Switchgear in underground Distribution networks or pole-mounted Load Break Switches (LBS) in Overhead lines. 8-feeder Switchgear Automation solution covered with only one Master and one Slave IEDs interconnected via IEC61850 protocol. Suitable for single busbar as well as multiple busbar substations.
