U/I combination sensor IKI-LUM-ISO-U  for non-shielded end closures of three-wire oil cable


In air-insulated switchgear, the installation of current and voltage sensors is often associated with increased effort, as these are not intended for design. Solutions with minimal installation effort are particularly in demand for retrofitting in plants without capacitive dividers.


The combined current and voltage sensor IKI-LUM-ISO-U enables current measurement and voltage detection in air-insulated switchgear with minimal installation effort.


Voltage test systems of the CAPDIS series as well as directional short-circuit and earth fault detection devices such as the IKI-22, IKI-23 or IKI-50 can be connected to the U/I combination sensor.


The most compact retrofit solution is the combination of fault direction detection and voltage testing with the device combination IKI-23_ CAPDIS-top.

Matching connection cables are pluggable and available in the following lengths :

  • 1.5 m
  • 3 m
  • 4.5 m
  • 6 m
  • other lengths on request

The connecting cables must be ordered separately.
