A. Incipient Fault/Failure Detection and Anticipation
U. S. Patent 8941387 "Apparatus and Method for Fault Detection and Location Determination" (January 27, 2015) -- Abstract: An electrical waveform is received over an electrical power line. A plurality of nominal electrical parameters are determined for the electrical power network and the plurality of nominal electrical parameters are associated with a state of the electrical power network in the absence of at least one transitory electrical fault in the network. Subsequently, a plurality of electrical parameters of the electrical waveform are sampled when the at least one transitory electrical fault exists in the network. A plurality of inductances are determined based at least in part upon a comparison of the nominal electrical parameters and the plurality of sampled electrical parameters. The plurality of inductances are representative of inductances present in the network when the at least one transitory electrical fault exists in the network. The plurality of inductances are analyzed to determine a distance and/or direction to the at least one electrical fault.

U. S. Patent 8711711 "System and Method of Detecting and Locating Intermittent and Other Faults" (April 29, 2014) - Abstract: Data associated with at least one building condition or status is sensed by one or more sensors. The data from theses sensors may be sent over a data bus and received by the central computer. In addition, a modulated signal may be transmitted by one or both of the transmitters across the data bus. The modulated signal is received at the receiver, which analyzes the received modulated signal, and determines whether an intermittent fault has occurred on the data bus based upon the analyzing. For example, the receiver may compare the received signal to an expected pattern and when a discrepancy exists, an intermittent fault is determined to exist. The receiver may also determine the location of the fault based upon the analysis.
