Omicron CP CU1 Multifunctional Coupling Unit for the CPC 100

Omicron CP CU1 Multifunctional Coupling Unit for the CPC 100

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.

Line and ground test system – CPC 100

• The CPC 100 is a multifunctional test set for primary assets.
  When combined with the CP CU1 it covers the following tests:
  Line impedances of overhead lines and power cables for
  distance relay parameterization
• Mutual coupling impedances between parallel lines
• Ground impedances of large substations
  (fall-of-potential or 3-point test)
• Step and touch voltages
• Reduction factor
• Coupling of power lines into signal cable

Your benefits

• High Accuracy: Frequency selectivemeasurement and digital filtering
• Safety: Galvanic isolation and protectionfrom overvoltages
• Light-weight and easy to handle
• Intuitive reporting and assessment withdedicated templates
• One unit for line and ground testing

Measurement advantages:

• Tune your distance relay by performinga line impedance measurement
• Safe and quick determination of Z1, Z0 and k-factors.
• Mutual coupling Impedance
  measurement between parallel lines

Personnel safety
In the event of a ground fault hazardous step and touch voltage can occur inside and outside of a substation. Ground tests prove the effectiveness of grounding systems and guarantee safety of people inside and outside the substation. A fall-of-potential measurement is usually performed to determine the condition of the entire ground grid. On top of that, step and touch voltages are measured at exposed
locations in order to ensure human safety
