Abstract
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.
Claims10
An apparatus for testing an electrical power system for anomalies, comprising:
- a computing device;
- a pulse generator having an output impedance greater than 500 ohms, the pulse generator configured to generate a pulse upon reception of a command signal from the computing device;
- one or more capacitive test sensors configured to be capacitively coupled to an on-line power component of the electrical power system, wherein at least one of the one or more capacitive test sensors receives the pulse generated by the pulse generator.
Dependencies are inferred from the claim text.
