Used with the Omicron CPC 100 Multi-Functional Primary Test System, the CP CU1 Multifunctional Coupling Unit measures line impedances and k-factors on overhead lines and power cables.

Ground impedances can also be determined on large systems with the CP CU1, as well as touch and step voltages.

Mains frequency malfunctions do not influence the measurements, as the CPC 100 and CP CU1 use variable output frequencies for measurements. This enables extremely precise and reproducible measurement results. 

This unit must be used in combination with the Omicron CPC 100 Multi-Functional Primary Test System.
