HYDROPOWER INDUSTRY GUIDE 2020/21 Company Profiles VUM Verfahren Umwelt Management GmbH Visual inspection, documentation and surveying using UAV`s (Unmanned Aerial vehicles) Lakeside B06 b AT Ι 9020 Klagenfurt am Wörthersee www.vum.co.at umwelttechnik@vum.co.at VUM Verfahren Umwelt Management GmbH (VUM) has been dealing with energy infrastructure (feasibility, approval, implementation, maintenance and aftercare) for many years. In particular VUM is increasingly pursuing the goal of incorporating innovation into its activities and deals with the use of remote sensing in the energy industry, particularly in the hydropower sector. VUM offers a wide range of drone-supported services. The experienced team has the specific expertise for status documentation visual inspections of technical infrastructure and aerial surveying as well as for the collection of environmental data. The information generated supports constructors, operators and maintenance staff of infrastructure in a variety of ways as decision support and forms an important basis for planning and documentation. VUM also deals with R&D-projects concerning aerial surveying. One focus is for example the development of a method for an extensive snow depth detection to improve snowmelt forecasts in alpine terrain. Our drone-experience especially in the hydropower sector is: • Inspection of technical infrastructure - Condition Monitoring at Power Plants and Power Lines • Environmental & Construction Progress Monitoring (surveying) - Digital Elevation Models, Volume and length measurement e.g. of excavation - Change Detection of terrain or surface e.g. Snow height measurement in alpine regions to improve forecast models - Orthofotos for visual documentation, comparison and surveying • Video- & photo- documentation - Image brochures, Illustrations, panoramic views Contact Corina Katzler Environmental & Project Management T +43 50 320 - 32 521 M +43 664 883 428 24 E corinna.katzler@vum.co.at Innovative Products and Services 112
HYDROPOWER INDUSTRY GUIDE 2020/21 Company Profiles VUM Verfahren Umwelt Management GmbH Insulation liquid analysis of high voltage equipment – Monitoring in the 21st Century Physico-chemical laboratory VUM Verfahren Umwelt Management (VUM) runs a physico-chemical laboratory specialized in the analysis of oil-immersed high voltage equipment (e.g. transformers). With more than 250 customers and manufacturer all over Europe and more than 25,000 analyzed specimen of high voltage equipment, VUM has built a strong and decade-long expertise on this field. VUM is a reliable partner for standard routine-analyses, state-evaluations, oil-regeneration and postmortem analyses, equipped with all necessary analytical tools according to the newest normative standards, highly-trained personnel and cutting-edge database-assisted evaluation technology. The analysis tool helps the customer to easily gain an overview about the status of their high voltage assets and compare them to historical data. This helps to formulate precise recommendations for future revision-measures wherever needed. The analysis tool also opens new possibilities for innovation, as the experts are now able to extract more information out of historical data. Taking analytical data from the database and combining it with environmental data, such as weather, temperature or geographical region can help to identify unknown risks and brings new possibilities and chances to improve existing routine methods and asset monitoring. Diagram - An exemplary Duval triangle generated with the data available from historical routine analyses, summarized and evaluated via the innovative VUM analysis tool for insulation liquids. This simplified and quick visualization enables the customer to evaluate the high voltage assets at a glance, indicating the evolution of a thermal fault. In this case, the customer had sufficient time to react upon the possible thread. The efficiency of the repair measures taken is easily visible respectively can be tracked in the analysis tool. Analysis tool for insulating liquids The 2018 newly launched innovative insulating liquid database improved customer-service even further. The software-assisted evaluation system combines the expertise of our chemists and engineers with an automated recognition system for electrical and thermal faults, alongside their exact categorization according to standardized criteria. The system utilizes acknowledged international methods and standards to display analytical data, graphical representations (e.g. Duval-triangle) and color-coded indications for the overall state of the analyzed assets. VUM strives to broaden the field of expertise and to face new challenges in the analysis of insulating liquids. VUM is also always open to engage in innovative research-projects and industrycooperation.
