The utilities spend a considerable amount for the maintenance, inspection, testing and monitoring of power infrastructure to achieve the above. The overhead power lines are the main power carriers for the delivery of electricity to the consumers. These overhead power lines are prone to risk of fires and faults caused by vegetation encroachment and touches on the power corridor, resulting in damage to the conductors, power blackouts and catastrophic events such as wildfires or bushfires. Therefore, utilities have to regularly inspect and monitor powerlines for the prevention of damage. Utilities have been adopting foot patrol, aerial inspections and more recently LIDAR technology to inspect the overhead power lines on regular basis. However, these approaches only give \"point of time\" information and are time consuming and costly. This paper presents a novel technique which uses directional antennas mounted on poles carrying overhead conductor to detect the partial discharge (PD) signals generated by incipient faults in an experimental set up and also field testing. These PD signals are processed by FPGA signal processing unit for peak detection and filtering and digest of the signals is delivered to a secured cloud server for post-data processing such as trend analysis, pattern recognition and localisation. This paper demonstrates the effectiveness of this Early Fault Detection (EFD) technique to accurately locate vegetation encroachment and partial discharge originated from broken insulators, defective gas switches and transformers. This technology has been successfully employed at various locations on distribution feeders in Australia and the results are very encouraging.","PeriodicalId":183797,"journal":{"name":"2019 IEEE 4th International Conference on Condition Assessment Techniques in Electrical Systems (CATCON)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115394883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As its performance in the network directly affects the reliability of the network, temporary/permanent outage results in interruption of power to the customers along with a loss of revenue. In order to avoid the said problem, this paper presents Sweep Frequency Response Analysis (SFRA) based technique that detects turn to turn shorts in the winding of the high voltage transformer. Unlike graphical analysis based conventional technique which needs expertise and experience of different people for fault diagnostic, the proposed technique is capable to detect and locate fault using statistical parameters that do not require expert advice. The simulation results as well as results obtained from the laboratory prototype of the transformer clearly indicate the effectiveness of the suggested technique in detecting and locating series and parallel faults in the winding of the high voltage transformer.","PeriodicalId":183797,"journal":{"name":"2019 IEEE 4th International Conference on Condition Assessment Techniques in Electrical Systems (CATCON)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121304180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
