Wire & Cable ASIA – January/February 2012

For all LAN, coaxial, telephone or RF
cables the loss-free transmission high
frequency, analogue or digital signals is
a major quality feature.
In this context, the measurement of the
capacitance plays an important role.
The capacitance influences the
impedance of the cable for the
specified frequency range, and thus
the quality of the cable, significantly.
Capacitance 2000 is a measuring
device which is installed in the cooling
trough and measures the capacitance
of the wire insulation precisely.
At the same time, the system
determines capacitance changes,
provides an extremely fast measuring
value update and detects bare wires.
This technology is realised by the
combination of one short and two long
measuring electrodes, which are
integrated in a measuring tube.
The short measuring electrode of
10mm length identifies periodical
capacitance variations with high spatial
resolution by means of Fast Fourier
Transformation (FFT).
