Small-Signal Sensor-Adapter

The IKI small signal sensor adapter enables the connection of IKI-LUM current transformers and the connection of an LRM interface / ohmic voltage sensors according to IEC 62271-213 to the IKI-55. Thus, in addition to the connection of standardised small signal transformers according to the IEC 61869-10 and 61869-11 standards, signals of a Capdis-Sx / ohmic voltage sensors and IKI-LUMs can also be connected to the IKI-55. In this way, the IKI-55 is also suitable for retrofit solutions for systems in which converters and Capdis-Sx are already pre-installed.

This version of the adapter allows the connection of a capacitive LRM interface (e.g. Capdis) and as a cross calibration input the connection of a precision voltage sensor with an output voltage of 3.25 / √3 V. The associated cable sets for connection to the IKI-55 can be obtained as accessories.
