Reliable impedance and k-factor measurements on power cables

CPC 100

Universal primary injection test set for substation assets

CP CU1

Coupling unit for injection into powerlines and HV cables

Benefits of this solution

Extremely accurate solution

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 precisely set the distance relays with impedance values and the calculated k-factor. This allows selective operation of the relay.

Variable frequency

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.

“With the CPC 100 + CP CU1, you can accurately determine the sequence impedance and K-factor setting needed for the distance protection relay on overhead power lines and cables.”
