摘要： A system for detecting partial discharge in electrical components may include a control system that may operate a drive in an industrial automation system. The industrial automation system may include the electrical components being analyzed for partial discharge. The system may also include one or more acoustic sensors that may detect one or more acoustic waveforms generated within at least one of the electrical components. The system may also include a monitoring system that may receive the acoustic waveforms from the acoustic sensors and determine whether the one electrical component is experiencing partial discharge based on the acoustic waveforms. The monitoring system may then send a notification to the control system when the one electrical component is determined to be experiencing partial discharge, such that the notification indicates that the one electrical component is experiencing partial discharge.

摘要： An apparatus (10) for detecting the occurence of partial discharge in electrical equipment, such as high voltage transformers. The apparatus comprises a detecting means including an ultrasonic transducer (11) mounted at one end of an electrically insulating elongate rod (13). The ultrasonic transducer (11) is adapted to detect ultrasonic pulses or waves generated by the occurence of a partial discharge in the electrical equipment. A radio frequency (RF) transducer (17) is also utilised to detect radio frequency (RF) pulses or waves also generated by the partial discharge. The rod (13) can be mounted in the wall of the electrical equipment and so provide a mechanism for adjusting the position of the detecting means within the electrical equipment. The apparatus is also removable from the electrical equipment and re-locatable to other equipment.

摘要： An apparatus (30) for detecting an electric arc (24a, 24b, 24c) in an electrical system (10) is provided. The apparatus facilitates localizing the position of the electric arc e.g., on component level. The apparatus comprises a sensor interface circuit (32) and one or more processors (34). The sensor interface circuit is configured to receive a signal originating from at least one sensor that is arranged in one or more positions in the electrical system for detecting an electrical current. The one or more processors are configured to analyze the received signal to determine a direction of the electrical current at the one or more positions in the electrical system, and to determine, based on the direction of the electrical current, an origin of the electric arc in the electrical system.

摘要： This application relates to methods and apparatus for determining the location of a fault (204) in a power cable (100) of a power distribution network. The method involves monitoring at least one electrical parameter of the power distribution network to detect the occurrence of a fault in the power cable and determine at least one time window (twin) for the occurrence of the fault. The fault may be detected by detecting opening of a circuit breaker (205). The method involves analysing a first set of measurement signals is obtained by a distributed fibre optic sensor (302) having a sensing optical fibre (301) deployed along the path of the power cable. The first set of measurement signals comprise signals indicative of the extent of any disturbances on each of a plurality of longitudinal sensing portions of the sensing fibre over a known time period. The measurement signals are analysed based on said at least one time window for measurement signals (502) indicative of a fault in the power cable and the location of the fault in the power cable is identified based on the location of one or more longitudinal sensing portions of the sensing fibre giving rise to the measurement signals indicative of a fault in the power cable.
