In the 1980s, SERECT, the RTE centre of expertise for live working, developed an Insulating Positioning Tower (IPT) to be able to carry out bare-hand live working in these sub-stations. Although the IPT was a revolution in its day, today it no longer meets the company's needs completely: neither in terms of ergonomics (climbing, access), nor in terms of design (tedious assembly), nor in terms of technology (silicone treatment, restricted use in a damp environment). With the benefit of these observations, SERECT has worked with France Elévateur to develop a Mobile Elevating Work Platforms for live working in very high voltage sub-stations (Sub-station LW MEWP). This MEWP uses the latest technologies. Ergonomics of the workstation are improved. It can be moved and positioned more rapidly and more precisely. The machinery is equipped with an insulating boom with fins, ready to be used; no assembly, no drying and no silicone treatment before starting work.","PeriodicalId":238060,"journal":{"name":"2014 11th International Conference on Live Maintenance (ICOLIM)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128051912","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}

This process requires the human resources division of the company, as well as supervisors and/or managers of the workers to apply a set of evaluation scores which include, Academic Qualification, Professional Training, Professional Experience, and the strategic relevance of each worker for the company.","PeriodicalId":238060,"journal":{"name":"2014 11th International Conference on Live Maintenance (ICOLIM)","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130038121","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}

{"title":"Twelve years of Live Substation Work at Powerlink Queensland Australia","authors":"J. Jouglard","doi":"10.1109/ICOLIM.2014.6934330","DOIUrl":"https://doi.org/10.1109/ICOLIM.2014.6934330","url":null,"abstract":"This presentation explains why Live Work was introduced in Powerlink substations in 2001 and how it has been used since. One measure of the performance of a transmission network resides with the reliability of both substation and line assets. Live Work on line assets is a mature practice that network owners have invested in to minimise interruptions to critical circuits. Powerlink's implementation of Live Work practices on substation plant provides a holistic approach to reliability and availability across the entire transmission network. Limited proven methodologies for Live Work in substation practices were available for evaluation considering the preferred option was an adaptable and safe approach based on specific risk analysis. Reseau de Transport d'Electricite's (RTE's) approach for Live Work in substations met Powerlink's requirements with regard to risk analysis as it uses a specific analysis for each task and environment. Performing Live Work tasks in a safe manner is dependent on using and applying suitable methods and tools and meeting general safety regulations and specific Live Working Conditions manual. The core of the Live Work Conditions manual was initially drawn up by RTE (SERECT; Service dedicated since 1962) which develops and markets specific tools according to the warranted characteristics presented in their Technical Sheets. At Powerlink, Live Work Hotstick and Barehand methods have been used safely and without incident for 12 years. With 14,000 hours of Live Work performed yearly, the Live Substation Team has 10 operators/team leaders accredited by Powerlink to perform Live Work. Live Substation Work is often selected as the preferred method for project and maintenance tasks for the 126 substations Powerlink has across Queensland. As a demonstration of Live Work skills and know-how, Powerlink presents a complex Live Work job at Tarong Substation: The objective was to increase the capacity of the 275 kV switchyard by installing additional bus-bar lengths in parallel to the existing buses in a vertical configuration. All operations involved the Live Substation Team, whilst maintaining the whole 275 kV switch yard operational; i.e. without any outages to the 275 kV buses and feeders and all tasks carried out under Live Work rules. The additional bus-bars have been put in place using crimped joints with welded tags. In total, the Live Substation Team carried out the placement of 48xlO m long bus-bars (totaling 480 m of bus length).","PeriodicalId":238060,"journal":{"name":"2014 11th International Conference on Live Maintenance (ICOLIM)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131738569","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}

The processes, which after exposure to moisture and the resulting leakage current reduce the electric and mechanic strength of insulating ropes, are of particular interest and insufficiently researched. Firstly, this paper describes the rope as an electric insulating system and presents significant processes at interfaces of ropes stressed by wetness in detail. Investigations on capillaries, which enable definitions of processes based on the waveforms of voltage and current, are explained. These results are compared with time profiles of voltage and current measured on ropes. In conclusion the results of the investigations on capillaries will be used for the classification of the processes in the ropes.","PeriodicalId":238060,"journal":{"name":"2014 11th International Conference on Live Maintenance (ICOLIM)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128703308","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}

The growing demand for arc protection PPE and its growing importance is reflected by high activity in standardization of arc protection PPE. That's why also the market is moving and presents costumer a wider range of products for all protection levels. The paper deals with special arc protection PPE which combine high protection level with high degree of ergonomics. It presents an algorithm and software tool for determining the necessary arc protection level of PPE for working places. Further more PPE will be presented which have an arc protection level beyond box-test class 2 to provide special protection for electrical work with higher risks of an electric arc e.g. switching operations.","PeriodicalId":238060,"journal":{"name":"2014 11th International Conference on Live Maintenance (ICOLIM)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124465715","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}
