Description
The Z-OVR Cable Impedance Test System is a reliable and powerful solution for measuring cable impedance accurately, whether it’s overhead lines or underground cables. This test set comprises a control unit and an output transformer that provides isolation of the output current and feedback voltage.
With the Z-OVR, you can inject current into the line under test and measure the resultant magnitude and phase angle of the voltage across the line. This measurement method allows for the calculation of the impedance (Z & X) of the line. The system displays the current, voltage, phase angle, impedance of the line, as well as the harmonic content of the voltage and current.
The Z-OVR has data logging capabilities to save date, time, current, voltage, phase angle, and frequency to a CSV file on a standard USB memory key. Additionally, the system provides three voltage taps (75V, 150V & 300V) for measuring a wide range of lines and cables, and all metering is true RMS.
The unit features four current ranges (2.000, 10.00, 20.00 and 100.0A) and three voltage ranges (10.00V, 30.00V, and 300.0V), and uses 6mm safety connectors for all outputs and 4mm safety connectors for inputs.
The Z-OVR Cable Impedance Test System also includes four 10m 12mm2 duplex measurement cables. Each cable has a 12mm2 conductor for current injection and a 6mm2 conductor for voltage feedback.
Our partners, which include Acutest, Alpha Electronics, Cuthbertson Laird, Norwich Instrument Services, and PASS Ltd, offer the Z-OVR Cable Impedance Test System in the United Kingdom. If you are based outside of Great Britain, you can order the product through our worldwide distribution network.

Good piece of kit, delivery time could be improved
Lianne Choringtone –
This test kit is quite heavy, it can be difficult to move around.
