A system for measuring the capacitance of an electric signal conductor, with particular interest on telephone cables. A waveform generator produces a test signal which is coupled to the conductor. The resultant signal emerging from the conductor is delivered to a receiver, and then to an integrator, to produce an output signal which is a direct digital measure of the conductor's capacitance.

Instruments and systems for measuring cable capacitances

An auxiliary test system for use with a long transmission line such as one having a telephone at an end thereof whereby from a remote central test station a line may be tested for a short between wires, an open, an abnormal load condition or reversed connections and the relative location of such a fault condition determined.
