Abstract: Sensor data immediately after the issuance of an alarm does not exhibit the peculiarity of a failure, with the result that the wrong component is sometimes erroneously identified as the failure component. A failure component identification unit provided in a maintenance device collects an alarm issued when a measurement value exceeds a range of a measurement threshold value in an apparatus being a maintenance target. The failure component identification unit identifies the failure component on the basis of the measurement value exhibiting a condition indicating a peculiarity of the failure. An identification reliability determination unit determines the reliability of the component identification result obtained by a failure component identification unit.

Abstract: Systems and methods detect steps from one or more sensed accelerometer signals. Systems comprise an accelerometer and a non-transitory computer readable medium, each of which communicates with a processor. The accelerometer is coupled to an individual and generates outputs received by the processor. The non-transitory computer readable medium stores instructions controlling the processor to perform steps of a method. The processor determines a minimum and a maximum reading for respective time periods. Counted peak heights are maxima that exceed a rest threshold. The rest threshold may be a function of the rest maximum. The processor determines a peak threshold for each time period having a counted peak height. A counted amplitude comprises the difference between the maximum reading and minimum readings of a time period in which the counted peak height exceeds the peak threshold. The processor increments a step counter when a counted amplitude exceeds an amplitude threshold.

Abstract: A method for determining the fault location of a ground fault relating to a line of a three-phase electrical energy supply network with an ungrounded neutral point, in which current and voltage values are measured at one line end of the line. Following the occurrence of a ground fault on the line, the location of the fault is defined using the measured current and voltage values. The measured current and voltage values are converted into ?-components and 0-components of a Clarke transformation, a location-dependent characteristic function of ?-component and 0-component fault voltage values is defined in each case using the converted components and a propagation model for travelling waves on the line. The fault location is determined to be the location at which the two characteristic functions exhibit the closest match.
