The method includes measuring an operating parameter comprising at least one of a phasor current and phasor voltage of an electrical machine. The method further includes determining a diagnostic parameter indicative of a fault of the electrical machine based on the measured operating parameter. The method also includes estimating end of life of the electrical machine based on the diagnostic parameter using an error minimization method.

Prognostics and life estimation of electrical machines

An arc flash detection method includes transmitting light via an optical fiber to a sensor and transmitting light from the sensor that includes components representative of acoustic waves and light for filtering and processing to detect an occurrence of an arc flash.

Arc flash detection method

A sensor to simultaneously detect light and acoustic waves is presented. The sensor includes one or more optical fibers and a diaphragm disposed near one end of at least one of the one or more optical fibers. The diaphragm is configured to vibrate upon incidence of acoustic waves from an arc flash and reflect a light beam into at least the one of the one or more of the optical fibers. A semi-transparent region is disposed around the one or more optical fibers to diffuse light originating from the arc flash into at least one of the one or more optical fibers.

Arc flash detection system and method

A protection relay with integrated communications may include a protective relay portion to perform protective relay operations associated with a load operatively connected to the protection relay, and a communications server portion to perform communications operations as an independently operating communications server.

Disclosed is a holding apparatus for a card used in a computing resource, the apparatus including a holding base, and at least one card associating arm extending from the base, the at least one associating arm being configured to hold the card via a screwless association.

Apparatus and method for holding a card

Disclosed herein relates to an enclosure-to-rail retaining system. The system includes, a rail that is fastenable to a structure, and an enclosure that is receptive of the rail. The enclosure has a slot therein that intersects a channel therein and is slidably engagable by a clip such that a portion of the clip can extend into the channel to thereby narrow a portion of the channel to a dimension less than a width of the rail.
