摘要： A measuring system, method, and/or computer program that realizes physics-based relations between sensor readings to monitor for degradations and predict failures of power systems is provided. For example, the supply and return of fuel in a power system is provided by a fuel injection system. The fuel injection system responds to changes in loads and system conditions, such as to compensate for fuel loss due to fuel combustion, by continuously and instantaneously changing the fuel flow. This behavior by the fuel injection system creates characteristic signatures. These characteristic signatures are instantaneously detected and utilized by the measuring system, method, and/or computer program to detect healthy, degrading, failing, and failed mechanical conditions so as to monitor for degradations and predict failures of the power system.

IPC分类号： G01R31/02
摘要： A method of electrical system fault detection and location determination includes measuring a baseline time domain reflectometry (TDR) waveform along a wire path of the electrical system and obtaining an operating TDR waveform along the wire path. The operating TDR waveform is compared to the baseline TDR waveform to derive a difference TDR waveform, and a difference energy is calculated utilizing the difference TDR waveform. The difference energy is monitored over time for peaks in the difference energy and potential electrical system faults are identified via the peaks in the difference energy.
