OMICRON CP-CU1 from Brandis Hire

The CPC 100 + CP CU1 measure line impedances and k-factors on overhead lines and power cables.

Category: Tag:


The CPC 100 + CP CU1 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


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

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. 

Key Features

  • Measurement is not affected by mains frequency interference extremely precise measurement
    results are obtained
  • Compliance with the strictest safety standards for overhead lines and cables connections diverting
    currents up to 30 kA
  • Easy to handle heaviest component: 29 kg
  • Automatic logging: Results are recorded automatically by the software 


  • Line impedances and k-factors of overhead lines or high-voltage cables
  • Ground impedances of large systems
  • Step and touch voltages
  • Mutual coupling of parallel overhead lines
  • Coupling of power lines into signal cables
