20110238329 | Method and a device for detecting abnormal changes in play in a transmission unit of a movable mechanical unit - The present invention relates to a method and a device for detecting abnormal changes in play in a transmission unit configured to transfer rotational movements of a motor, having a speed of rotation that depends on a torque reference signal (T | 09-29-2011 |
20120004867 | SYSTEMS AND METHODS FOR CHARACTERIZING FAULT CLEARING DEVICES - Systems and methods for characterizing a device that operated to clear a fault in a power line, such as a power distribution system feeder, are disclosed. Characterizing the device may include receiving measured data corresponding to a current measured along the feeder proximate a substation bus, determining from the measured data that a fault has occurred in at least one phase and has been cleared, subtracting reference data from the measured data to estimate residual fault data, and estimating from the residual fault data a characteristic of the device that operated to clear the fault. The systems may include an Intelligent Electronic Device (IED) and a processor linked to the IED. | 01-05-2012 |
20120004869 | SYSTEMS AND METHODS FOR POWER LINE EVENT ZONE IDENTIFICATION - Systems and methods for power line event zone identification are disclosed. Power line event zone identification may include receiving measured data corresponding to a signal measured on a power line, determining from the measured data that a power line event has occurred, and identifying a probable one of at least two monitoring zones in which the power line event occurred. The at least two monitoring zones may be defined for an Intelligent Electronic Device (IED). The systems may include an IED connected to the power line and a processor linked to the IED. | 01-05-2012 |
20120010830 | SYSTEMS AND METHODS FOR CLASSIFYING POWER LINE EVENTS - Systems and methods for classifying power line events are disclosed. Classifying power line events may include receiving measured data corresponding to a signal measured on a power line, such as proximate a substation bus or along the power line, determining from the measured data that the power line event has occurred, extracting at least one event feature from the measured data, and determining at least partially from the at least one event feature at least one probable classification for the power line event. The systems may include an Intelligent Electronic Device (IED) connected to the power line and a processor linked to the IED. | 01-12-2012 |
20130194299 | METHOD AND SYSTEM FOR MULTI-IED EVENT CLASSIFICATION IN AN ELECTRICAL GRID - A method for providing a navigation tool of a user interface for an industrial control system. The control system is arranged with a plurality of process graphics including one or more software objects. The software objects are arranged in hierarchical groups each representing a process, part-process or an equipment, in which materials are moved and/or processed in a predetermined order. The navigation tool includes a graphic image or map showing the plurality of process graphics symbolically arranged as a plurality of nodes. Each node is spatially arranged at a given distance from the centre of the map according to a hierarchical relationship between the process graphics, and the map is displayed superimposed on top of the process graphic currently displayed on the workstation. | 08-01-2013 |
20130198124 | METHOD AND SYSTEM FOR MULTI-IED EVENT ZONE IDENTIFICATION IN AN ELECTRICAL GRID - A method of identifying at least one event zone subject to an event in a substation environment of an electrical grid. Thereby, data from multiple intelligent electronic devices can be synthesized in real-time whereby an operator can be presented with a single conclusion describing the event attributes thereby helping the operator to determine the mitigation actions as needed. The method includes receiving first event related data from the intelligent electronic devices, and based on the first event related data, determining whether the at least one monitoring zone subject to the event is a primary monitoring zone of at least one of the intelligent electronic devices or a non-primary monitoring zone for all of the intelligent electronic devices using ensemble decision making and probabilistic methods. It is also presented a system for carrying out the method. | 08-01-2013 |
20140222352 | Condition Monitoring Of An Industrial Robot - A method for detecting a fault in a robot joint includes the steps of: performing a first torque measurement at the robot joint to thereby obtain a first set of torque values; calculating a first distribution characteristic reflecting a distribution of the first set of torque values; performing a second torque measurement at the robot joint to thereby obtain a second set of torque values; calculating a second distribution characteristic reflecting a distribution of the second set of torque values; and comparing the first and the second distribution characteristics to determine whether a fault is present or not. A difference in the distributions of torque measurements is a robust fault indicator that makes use of the repetitive behavior of the system. | 08-07-2014 |
