Omicron CPC 100 All-In-One Test System – Part 5 Power Line Testing

Omicron-CPC-100For a reliable power supply, selective operation of protection relays is crucial. Over- and underreach can be avoided by having correct relay settings, and line data.

Therefore it is necessary to determine line parameters, such as positive sequence impedance, zero sequence impedance or k-factors.

Calculating impedances and the k-factor is highly error prone. Measuring line and ground impedance eliminates these errors and contributes to system reliability by providing proper relay settings. 

With the Omicron CPC 100 Multi-functional Primary Test System and the CP CU1 the impedance of cables and power lines can be measured accurately, quickly (in approximately two hours) and safely.

The CPC 100 and the CP CU1 are used to inject current into the different phase-phase and phase-ground loops of a power line / cable, grounded at the other end, while measuring voltage, current and phase angle. From the measurement data of the different loops, line parameters are calculated. Variable frequency injection allows measurements to be made despite coupling from live parts or neighboring lines.

With this unique testing equipment, the mutual coupling factor of parallel lines can also be determined, allowing the correct parameterization of the mutual coupling algorithm of modern line protection relays.

Cable and transmission line diagnosis:

• Line impedance and k-factor up to 100 A | with CP CU1

• Mutual coupling up to 100 A | with CP CU1

• Positive or zero sequence impedance
