The CP CU1 is a coupling unit that is used in conjunction with the CPC100 for line and ground testing including:
- 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 cables
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
