A method for predicting time-to-failure and remaining-life of an electrical power system asset includes analyzing characteristics of the power system asset over a specified time interval; based on the analysis, associating the power system asset with a pool of similar power system assets having similar historical performance characteristics; and based on the association, calculating time-to-failure and remaining-life probability factors for the power system asset. A computer program product is also provided for carrying out the method, and the method may further include a mechanism whereby the computer program learns ways to modify and enhance the analysis of the performance characteristics to provide for higher confidence levels in time-to-failure and remaining-life probability calculations.

A technique for performing condition monitoring of a plurality of components of a plurality of wind turbines is disclosed. The technique includes, for each of the plurality of wind turbines, measuring at least one time-series electrical output signal of the wind turbine generator, each time-series electrical output signal representing an aggregate of a plurality of subset signals. Such condition monitoring further includes mathematically extracting one or more such subset signals from the at least one time-series electrical output signal of the generator, and associating one or more such subset signals with one or more wind turbine components. A fault threshold value for each such one or more subset signals may be determined, and the one or more such subset signals are compared to such fault threshold value. Based on such association and comparison, the condition of such a wind turbine component of the plurality of wind turbines is determined.

A device, which may be embedded in a power distribution enclosure, enables analysis of the conditions of an electromechanical machine operating on a commonly supplied network with other electromechanical machines. The analysis preferably uses aggregate operating voltage and current signals supplied to or from such machines along with known changes in steady-state conditions of one or more machines to discern the discrete effect of one or more machines to the aggregate electrical signal. Such discrete effect can then be associated with the operating performance of the individual machine. And, since such voltage and current signals are normally readily available at the enclosure, wiring or any other communication means to any sensors on the electromechanical machines or devices are not necessary. The embedded device may optionally receive or transmit information to a computing or monitoring device remote from the enclosure.

A method for enabling a user to submit proposed photos of the user, remotely, and in confidence, to a peer user to have the peer user review and rank each of the photos in order of preference, and to receive the results of the review and ranking made by the peer user. The peer user feedback may be then considered in assisting the user in determining which photos the user should upload to a given social media website to portray the user.

An upgradeable test set is that includes a stimulator circuit to transmit test signals to an electrical equipment under test, a coupling to removeably couple at least the stimulator circuit to one of a plurality of front-end interfaces. The plurality of front-end interfaces include a first front-end interface having a first display and a first input device and a second front-end interface having a second display and a second input device. The first display and the second display have different display characteristics, and the first input device and the second input device have different characteristics. The one of the front-end interfaces communicates a test control parameter to the stimulator circuit and a response of the electrical equipment under test is communicated to the one of the front-end interfaces. The case is configured to enclose the stimulator circuit, the one of the front-end interfaces, and the coupling.

The present invention is an attachment device and a method for fastening and removing an electrical cable monitoring instrument to an electrical cable. The attachment device comprises monitoring instrument sensor with opening for positioning electrical cable such that said electrical cable can be positioned to pass through the sensitive volume at least partially surrounded by said sensor, at least one elongated elastic member securely attached to said cable monitoring instrument such that, when elastically deformed to a shape characterized by high mechanical energy such that deformed elastic member allows said electrical cable access to and from the sensitive volume at least partially surrounded by said monitoring instruments sensor. The elongated elastic member, when relaxed to the a shape characterized by lower mechanical energy than high mechanical energy shape, with the electrical cable positioned to pass through sensitive volume, applies elastic force to the electrical cable to hold the electrical cable passing through the sensitive volume firmly and securely in contact with the cable monitoring instrument with no relative motion.
