Product information "IKI-Overhead Radio"

Error detection of all typical overhead line faults

  • Short-circuits, transients and earth faults

Ultra bright LED indicator

  • Visibility cone 360°, visible even in bright sunlight

Easy installation by means of actuating rod

  • The built-in torque indicator displays the correct installation. No additional tools required.
  • All communication elements are installed directly in the overhead line indicators. Therefore, no additional telecontrol unit mounted on the mast is required.

Reliable fault detection

  • By independent current/time characteristic (UMZ); Short-circuit and earth fault detection; Detection of high-impedance faults by dI/dT capture; Inrush suppression; Fault confirmation by monitoring for shutdown via integrated voltage sensor

Simple setting of parameters with DIP switches

  • Response current (automatic or fixed thresholds 200 - 600 A).
  • Reset time (2 - 8 h, manually or automatically after load current return). Access to DIP switches without tools possible.    

Long service life

  •  Through high-quality lithium battery, nanowatt technology and corrosion-free housing.


Simple connection to the control center via IEC 60870-5-104

  • With the optionally available SMS gateway, all installed IKI overheads are connected to the control center or the PONLINE system and integrated.

Detection of conductor breakage in overhead line

  • Detection of conductor interruptions without fault current

Transmission of load current values

  • Current or mean values are transferred cyclically

Remote parameterization of the settings possible

Communication principle

  • Up to 8 IKI overhead radios communicate with an IKI-overhead-butler via close-range radio. The IKI-overhead-butler communicates via GSM with the PONLINE master server or any SMS receiver. The PONLINE-Mater server can be integrated via an IEC 60870-5-104 into a control room.

Principle of fault detection with remote message

  • The faults are displayed up to the point of failure.

Display of all relevant status information

In conjunction with PONLINE, all important information (faults and load flow) from the overhead line network, such as all types of faults and load flow information, is collected and transmitted.
