Abstract:

Cabling faults can be difficult to identify and locate when a large number of interconnections are used such as in the shipboard Machinery Control System. Ungrounded systems further complicate diagnosis, since signal voltages and currents are small amplitude. It often takes a considerable amount of time to identify and locate the fault, and the equipment capability can be substantially reduced while troubleshooting occurs. We propose to develop a low-cost ground fault detector and locator which dramatically reduces time required to identify and locate the problem. Our concept has been developed specifically for ungrounded systems, and this method allows rapid isolation and convergence to the exact nature and location of the problem. This method can be implemented either as a low-cost handheld diagnostic tool, or as part of an integrated continuous real-time health monitoring system. Operational costs will be reduced by (1) quickly identifying which cable has the problem, (2) locating the exact location of the problem, and (3) prompt remediation. In Phase I we will develop a prototype to demonstrate feasibility, and during Phase II we will fabricate systems for further evaluation. Data will be correlated with inspection results to determine the effectiveness of the approach.
