Conventional calculations of line impedance values are highly error-prone. By combining the CPC 100 and CP CU1, you can perform extremely accurate measurements of the sequence impedances.
Correct relay parameterization
The data provided allows you to set the distance relays precisely with impedance values and the calculated k-factor. This allows selective operation of the relay.
The compact, lightweight system – the heaviest component weighs 29 kg / 64 lbs – can measure values at variable frequencies. Thus, the effects of power system frequency can be eliminated.
High level of safety
To protect you and your equipment, the CP CU1 comes with the CP GB1 grounding unit. This unit can divert currents of up to 30 kA if its voltage limit value is exceeded due to unexpected induced potentials on adjacent lines.
