OMICRON CP CU1 Coupling Unit for Substation Grounding Analysis

The CPC 100 and OMICRON CP CU1 Multifunctional Coupling Unit measure 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 + CP CU1 use variable output frequencies for measurements. This enables extremely precise and reproducible measurement results. To increase safety for the test engineer, the CP GB1 grounding unit is supplied with the CP CU1. This can divert currents of up to 30 kA if its voltage limit value is exceeded.
