Jenkins sold a Jenkins Motor Test System to Oman, where temperatures can exceed 120ºF. While Jenkins Motor Test Systems are built tough and for industrial environments, this specific location required customizations to be the most effective in an extremely hot environment. Locations near large bodies of water or tropical environments can also cause problems as the humidity in the air will cause the copper wiring in the transformer to oxidize over time. Although Jenkins designs its equipment to operate for long periods, some applications for customer environments require specific customization. The Solution  Jenkins engineers and winders worked together to develop a custom solution for this harsh climate, particularly paying close attention to temperature and water resistance. To customize the transformer for this environment, the Jenkins team made the following modifications: Doubling the spacing between winding layers to increase airflow. Encasing the transformer first in a high tolerance epoxy varnish, and then in a polyester over-dip that prevents the application from rust, dust, and harmful materials. Utilizing expanded metal at the base of the MTS enclosure, allows heat to escape, reducing the internal temperature. Installing temperature-sensitive cooling fans (set to 100ºF) atop the enclosure to prevent overheating. The Results  Jenkins technicians checked insulation for 10,000 volts (resistance to ground), checked each voltage leg, and high voltage potential to ground, and ensured the taps were in the correct place. Voltage was confirmed to operate up to 20% above normal operation, ensuring maximum efficiency and longevity of the transformer. These modifications have resulted in prolonged use of the Jenkins Motor Test System in harsh environments and ultimately customer satisfaction.

Siemens has developed a digital twin especially for large event spaces. The technology makes it possible to realistically reproduce and simulate very precisely a building’s acoustics and structure. The Sound of Science application will be used for the first time in the Großes Festspielhaus – the Large Festival Hall – at the Salzburg Festival. Sound of Science application Orchestral formations on the stage can also be tested and arranged in advance Sound of Science will enable event organizers to virtually explore how acoustics change in different spatial configurations – for example, how adding acoustic panels affects the listening experience – in order to select the optimal acoustic scenario. Orchestral formations on the stage can also be tested and arranged in advance – before a single note is heard in the real world. This approach saves money, resources and time. Siemens to use digital twins “With Sound of Science, we’re designing the future. Digital twins are not only transforming the everyday for many companies, but are also creating new opportunities for the cultural and creative industries,” said Prof. Dr. Stephan Frucht, Artistic Director of the Siemens Arts Program. Dr. Stephan Frucht adds, “In the future, we’ll be able to plan stage productions better and even simulate them acoustically in advance. We’re delighted to have the Salzburg Festival at our side as a long-standing partner, who recognizes the opportunities such innovations offer.” Sound of Science app for select partners Siemens will make the Sound of Science app available to selected partners from the cultural world free of charge as a demonstration application. There are currently no plans to market the application. Its simulation solutions, however, may be purchased. The Salzburg Festival’s Großes Festspielhaus is the first and only large event space to date in which Sound of Science is available. However, Siemens is planning to digitally simulate further spaces – including concert halls in Germany and England. At the Salzburg Festival, audiences will have an opportunity – unique for the time being – to use VR glasses to experience the application at the festival’s opening on July 20. Siemens and the Salzburg Festival “Siemens and the Salzburg Festival share a common passion for excellence and innovation. And we’re delighted to partake in this pioneering technological development and innovation as part of our long-standing close and trust-based partnership,” said Dr. Kristina Hammer, President of the Salzburg Festival. Dr. Kristina Hammer adds, “We’re excited to see what diverse applications will stem from Sound of Science in the future.” Siemens Simcenter’s simulation solutions The technologies used are part of the simulation solutions from Siemens Simcenter The technologies used are part of the simulation solutions from Siemens Simcenter, which has been part of the company’s core business for over 15 years. The technology is mostly used in industry – for example, for the acoustic optimization of vehicle interiors or for protection against street noise. For Sound of Science, Simcenter uses a combination of impulse response measurements and ray tracing for the 3D modeling of each event space. These methods can measure the echo and reverberation of a sound and simulate how sound waves propagate in a room. Depending on the material, reflections of sound waves behave differently. Those that bounce off a concrete wall react differently from those that hit a carpet or reach the ear directly. As a result, the simulation can reproduce the individual sound signature of each event space – in other words, its acoustic DNA. Siemens Festival Nights Siemens has been working closely with the Salzburg Festival for around 30 years. Since 1999, the company has also been the festival’s main sponsor. Since 2002, the Siemens Festival Nights have been held on Kapitelplatz square during the Salzburg Festival. Since its beginning, this open-air event has provided more than one million visitors with the opportunity to experience previous and current festival productions on an LED screen free of charge. In addition, some of the Salzburg Festival’s venues are equipped with Siemens technology from the areas of building automation, security and acoustics.
