摘要： A number of TDR systems and testing methods are provided that improve the quality and accuracy of information collected when propagating a signal along a length of cable in order to pinpoint specific anomalies. One or more of the TDR systems includes, for example, a computing device, a pulse generator, and at least one capacitive test sensor. The at least one capacitive test sensor transmits/receives pulses to/from a power system component, such as an insulated power cable, in a capacitive manner.

摘要： A capacitor component is adapted for capacitive coupling to an electrical power apparatus in which a PD is suspected, such as a shielded power cable; and an impedance transformance device has an input side connected directly to the capacitor component. Together the two components are used as a sensor to pick up and convey PD signals to a PD signal-analyzing system. Although the two components inherently form a classic high-pass RC filter, in accordance with the invention the input impedance at the capacitor side is much greater than the output impedance at the signal-analyzing system side. The effect is to pass much more of the lower frequency components of the PD signal for analysis by the PD signal-analyzing system than if the tranformance device were not included.
