MV Overhead and Underground Grid Remote Terminal Unit (RTU)


IControl-T / Medium Voltage SCADA remote terminal unit is an interface ensuring optimal management (remote control and monitoring) of distribution networks.

Main characteristics

Combined with one or more motorised MV switches, the Switch Remote Control Interface (IControl-Tx) offers:

  • local or remote network reconfiguration
  • network monitoring and remote reporting of MV faults, regardless of the neutral point connection
  • the network’s lead-through
  • automatic power source permutation (PASA function for double bypass powered substations)

This switch remote control terminal unit is built in a modular fashion to meet the various needs of customers:

  • Controls up to 16 switch switchgears
  • Battery backup power Adaptable power supply voltage
  • Communication protocols: IEC 101 / IEC 104 / DNP3 / MODBUS / HNZ, etc.
  • Communication media: RTC / GSM-GPRS / private radio network
  • Fault detection: amperometric or directional
  • Logging of dated events
  • Remote measurements
  • Integrated automation, such as PASA (automatic power source permutation) and ADA (automatic opening in voltage dips)


  • Optimised electricity distribution network management for improved service continuity
  • Compatibility with all market MV boards and overhead MV switches
  • All necessary functionality available for local or remote operation of MV structures with motorised switches
  • Modular and compatible with all types of communication media and monitoring systems (SCADA)
  • Configuration and settings through an onboard web server


  • Public distribution network
  • Private network (industrial, renewable energy, etc.)
