A Novel Pulse Echo Correlation Tool for Transmission Path Testing and Fault Diagnosis
Abstract-- In this paper a novel pulse sequence testing methodology is presented [22] as an alternative to Time Domain Reflectometry (TDR) for transmission line health condition monitoring, faultfinding and location. This scheme uses Pseudo Random Binary Sequence (PRBS) injection for transmission line testing and fault location with cross correlation (CCR) techniques to build a unique response profile, as a characteristic signature, to identify the type of fault, if any, or load termination present as well as its distance from the point of stimulus insertion. This fault characterization strategy can be applied to a number of industrial application scenarios embracing high frequency (HF) printed circuit board (PCB) and integrated circuit (IC) device operation, overhead lines and underground cables in inaccessible locations, which rely on a transmission line pathway or via common to all cases either for signal propagation or power conveyance. As an improved time-domain methodology PRBS e...
