IKI-Overhead R2.5 (Set)

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. The set consists of three units (2 x IKI-Overhead-Radio and 1 x IKI-Overhead-Butler) for three-phase monitoring at one installation location.

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. Installation is possible with operating rods for bayonet or ring eyelet, an adapter is supplied with each.

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

>10 years due to high quality lithium battery, nanowatt technology and corrosion-free housing.

Easy installation

Torque indicator for safe mounting

IKI overhead with remote messaging: Radio and Butler versions

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

4G-Modem

The modem integrated in the IKI-Overhead-Butler, can use 4G LTE-M / NB-IoT networks.

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

With the optionally available PONLINE-Gateway, all installed IKI overhead are connected to a SCADA-System.

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 the 4G LTE-M or 4G NB-IoT mobile network. Communication takes place either via SMS or TCP/IP to the PONLINE-Gateway or any SMS receiver or host. The PONLINE-Gateway can be connected to the SCADA 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

All important information (faults and load flow) from the overhead line network, such as all types of faults as well as load flow information, is recorded and transferred.

Set of three devices

The set of three (article number 2510699) consists of two IKI-Overhead-Radio devices (article number 2501307_H022) and one IKI-Overhead-Butler device (2501309_H022). This enables three-phase monitoring of one installation location.
