Abstract
A capacitance monitoring system includes a capacitance gauge head for monitoring the capacitance between a measuring electrode and an electric cable travelling along a path parallel to the measuring electrode. The output from the capacitor gauge head is fed to a Fast Fourier Transform device ( ) to produce, to indicate discrete cyclical faults in the cable and the frequencies to which they would be relevant. A cable speed detector ( ) feeds a reference table device which stores different correction factors to correct the amplitude of the cyclical faults detected due to the attenuation imposed on the measured signal because of the specific length of the electrode. A multiplier ( ) multiplies the cyclical fault signals detected by the relevant factors from the reference table device ( ).
