Product information "IKI-LUM-ISO-U"
The sensor IKI-LUM-ISO-U combines the functionality of the current sensor type IKI-LUM-ISO and the voltage sensor CAPDIS-Sense. The voltage sensor output may only be used in conjunction with voltage detection systems of type CAPDIS. If voltage measurement is required, we recommend cast resin coupling electrodes. The combined sensor is the perfect combination for retrofit applications in combination with the IKI-23 plus CAPDIS_top.


The voltage decoupling of the combination sensor detects the potential of the unshielded part of the cable termination. Capacitive decoupling of the voltage signal is not possible on fully shielded terminations, therefore the combination sensor cannot be used in this case. The voltage output is connected directly to a CAPDIS. The current is measured via a sensor current transformer with transformation ratio 2000/1. The current output is connected directly to an IKI 22, 23, 35 or 50 etc..

Easy retrofit


Current and voltage signal are combined in one sensor

Ideal in combination with the IKI-23


IKI-23 plus CAPDIS_top combine fault direction detection and voltage absence testing in one device.

For three-core cable terminations 6 - 13.8 kV

Suitable for e.g. unshielded three-core cable terminations of oil cables.
