Product information "IKI-Overhead R2.5"
With the IKI-Overhead R2.5, overhead lines can be easily monitored for faults and thus integrated into the overall protection concept to minimize downtime. Fault indication is provided locally via strong LEDs and optionally via remote transmission to a central control station.

Fault detection of all typical overhead line faults

Short circuits, transients and ground faults

Ultra-bright LED display

Visibility cone 360°, visible even in bright sunlight

Easy installation using actuating rod

Integrated torque indicator shows correct installation. No additional tools required.

Reliable fault detection

for overcurrent and short-circuit due to independent current/time characteristic; short and earth [short] circuit detection; high impedance fault detection by dI/dT detection; inrush suppression; fault confirmation by monitoring for disconnection via integrated voltage sensor

Simple parameter setting by DIP switch

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

Long life

due to high quality lithium battery, nanowatt technology and corrosion-free housing.

Easy installation

Torque indicator for safe mounting


The modem integrated in the IKI-Overhead-Butler, can use 4G networks.

Remote signalling: Radio and Butler versions

All communication elements are directly installed in the overhead line indicators. Therefore, no additional telecontrol unit mounted on the pole is required.

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

With the optionally available SMS gateway, all installed IKI overhead R2 are connected to the control center or the PONLINE system and integrated

Detection of conductor breakage in the overhead line

Detection of conductor breakage without fault current

Transmission of load current values

Instantaneous or average values are transmitted cyclically

Remote parameterization of settings possible

Communication principle

Up to 2 IKI overhead radios communicate with one IKI overhead butler via short-range radio. The IKI overhead butler communicates via GSM with the PONLINE master server or any SMS receivers. The PONLINE master server can be connected to the control room via an IEC 60870-5-104 interface.

Principle of fault detection with remote signalling

Faults are detected and reported right up to the fault location in each case

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 recorded and transmitted.
