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: An injection protocol for a cable includes selecting a cable for testing, selecting a pre-injection electrical discharge test for determining if electrical discharge activity occurs at or about operating voltage of the cable, configuring the cable for the pre-injection electrical discharge test; running the pre-injection electrical discharge test on the cable, and determining whether to inject the cable with a restorative fluid based upon electrical discharge activity detected at or about operating voltage of the cable.
