In order to achieve the task already existing live working technology related to overhead MV distribution lines using the lift with isolation arm and the technology of live working on LV devices has been used. Work related with installation of devices mentioned above is a process, which has a few steps. In the first step, which had to be done before live working is selection of overhead current transformers (CT), installation of LV measuring balancing cabinet and wires in protection tubes on supporting structures of the MV/LV pole substation. The next step is to insulate the work zone for both the MV and LV level, which starts part of live working task. What needs to be done next is mounting CTs on cable. The installation of CT could be done in two ways: after turning off the LV receiver circuits or with using the insulated shunt. The next step is connection of voltage wires in LV balancing measuring cabinet. The final step is to remove insulation of work zone after checking proper execution of the task. The paper also describes problems that were faced in process of development of live working technology. During execution of the tasks it occurred that there was a problem with loosening transformer terminal screws of one of the manufacturers, commonly used in Poland, while using conventional insulated spanner. The maneuvers using available tools were not possible due to very small distance between transformer's LV bushings. The solution was found in developing new insulated spanner which would meet the requirements of live working technology and enable executing the task. There was also a need to develop a new insulation sheet for LV bushings of transformer.","PeriodicalId":238060,"journal":{"name":"2014 11th International Conference on Live Maintenance (ICOLIM)","volume":"27 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":"127786842","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":"RTE and live substation work at powerlink queensland","authors":"M. Laugier, L. Devatine, J. Jouglard","doi":"10.1109/ICOLIM.2014.6934345","DOIUrl":"https://doi.org/10.1109/ICOLIM.2014.6934345","url":null,"abstract":"This presentation shows how RTE introduced Live Work (LW) within Powerlink substations in 2001. One measure of performance of a transmission network resides with the reliability of both substation and line assets. LW on line assets is a mature practice that network owners have invested in to minimise interruptions to critical circuits. RTE's LW practices on substation plant provide a holistic approach to reliability and availability across the entire transmission network of Powerlink. RTE's approach for LW 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 suitable means and tools and applying both, meeting general safety regulations and specific Live Working Conditions (LWC). LW Hotstick and Barehand methods have been used safely in France for 50 years. The LWC were 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. In France, the annual activity in HV LW represents, on average, 160,000 hours of work, or more specifically 85,000 hours in substations, and 75,000 hours on overhead lines. There are: (1)21 LW Overhead Lines teams and 165 linesmen, including 72 for Helicopter LW, (2)19 LW Substations teams and 142 operators. The consistent framework of areas for LW interventions defines the criteria for carrying out on-site work (strategic facilities, busbars... ). RTE has perfected a methodology which is unique and can be adapted to all countries. This method begins with an in-depth analysis of the client's needs and ends with operational monitoring of the new team(s). The aspects examined are: the management, activities carried out in \"dead work\" conditions, operational rules and the protection system. The LWC and the training are then adapted to the country's regulations. The tools sold, are developed and warranted by SERECT in accordance with the relevant lEe. All of these tools are then subjected to qualification tests in SERECT's LW laboratory. In addition to this, agreements can also be established to provide assistance to the teams which have been trained. This paper is split in three parts respectively presented by RTE SERECT for the story of LW in France, RTE International for the transfer of knowledge and methodology and Powerlink for the feedback and results assessment.","PeriodicalId":238060,"journal":{"name":"2014 11th International Conference on Live Maintenance (ICOLIM)","volume":"696 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":"132307496","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}

It applies in particular to construction of roads, railroads, sports and cultural facilities, including highways, sports stadiums, which leads to installation of cables on various lengths of sections, which frequently enter dense built-up areas of urban agglomerations. Expanded infrastructure, formal-legal regulations cause difficulties to acquire land for overhead lines. Therefore, despite higher costs, projects involve installation of 110kV-400kV cable lines more often than in the past. The most frequent projects involve construction of 110kV cable lines, which cost is nearly twice as high as overhead lines. Installation of cable lines requires high quality installation works, including heads on line poles and support structures of stations. In order to avoid inconvenient outages, electrical companies conduct concept works in order to install heads on live lines. These works are described in this paper. It discusses the principles of occupational safety and the risk involved in this type of works.","PeriodicalId":238060,"journal":{"name":"2014 11th International Conference on Live Maintenance (ICOLIM)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128116368","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}

But, due to different regulations and practices in each Country, it is impossible to know simply what skills a ≪ foreign ≫ electrician has. So is born the idea to design some international codes to facilitate this identification. The aim of this work, realized by a working group under the leadership of ISSA, is to easily identify the main electrical competences of electricians concerning dead or live work, on overhead lines , cables, work in substations, customer's connection or mobile generator connection. It does not replace the safety regulations and procedures that are in place. It is an additional approach used when necessary. Based on an intuitive approach using pictograms, it avoids any difficulty of understanding due to the language. It allows, in a simple way and very quickly, to a company which welcomes electricians from a foreign company to know what are the skills recognized by his employer and the type of work which he could done for a better employment of the staff.","PeriodicalId":238060,"journal":{"name":"2014 11th International Conference on Live Maintenance (ICOLIM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129540593","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}

Therefore, EDP wants to have a more active role in the conservation and the promotion of the natural Flora and Fauna. Continuing with the practice of defending the values of environmental preservation and quality of life, the company adopts, among others, the commitment to adapt its actions to the needs of biodiversity protection. The existence of thousands of km of Medium Voltage (MV) networks where lines are supported by rigid insulators requires a careful analysis of the factors that impact the quality of service of this type of technical assets. Despite being a discontinued technology, at least in Portugal, it is our mission to maintain and, if possible, increase the useful life of this asset. Unfortunately, the distance between the line and the pole arm is small, increasing the risk of electrocution of animals, mainly birds. The reduction of the number and duration of incidents which cause more or less prolonged interruptions in power supply at the customers' level, with negative impacts on production processes, especially those of sensitive technologies, is an increasing concern at EDP Distribution. The EDP Distribuicao's Network Maintenance and Technology Departments, together with Visabeira contractor, intends to perform an experiment with the objective of covering the conductor and tie through live working procedures. The conductor will initially be coated with a RTV mastic tape and, at a second stage, by a RTV silicone tape. The tie will undergo the same treatment.","PeriodicalId":238060,"journal":{"name":"2014 11th International Conference on Live Maintenance (ICOLIM)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124679283","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}

EDP Distribuição started live-line working (LW) on MV overhead lines during the 1970s and progressed to HV lines (60 kV) in 1998. The LW techniques (hot stick) have also been applied in substations, first in MV and, for more than a decade, in HV, mainly in the establishment of temporary circuits, in the removal or placement of bus bar sections, and also in connection of MV or HV equipment, always with the aim of not interrupting the power supply to customers. The present paper describes a replacement of two poles of a HV isolator suffering from overheating on different metal contact zones, and carried out by EDP Distribuição teams during the summer of 2013. The option of using LW techniques was imposed by the particular conditions of that substation. It was a site without redundancy in HV feeders, with sensitive industrial loads and with limited capacity to support the loads by MV lines.","PeriodicalId":238060,"journal":{"name":"2014 11th International Conference on Live Maintenance (ICOLIM)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128824822","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}
