Powerful view to the stars: Siemens delivers power substations to Observatory

The Very Large Telescope (VLT) array in Chile is part of the Paranal Observatory and it is the world’s most advanced optical instrument

The compact stations are modular substations, prefabricated and pre-tested on a customer-specific basis, for reliable power supply. Siemens will install 8DJH medium-voltage switchgear, Sivacon S8 low-voltage switchgear and transformers in the compact stations for the European Southern Observatory. The compact stations from Siemens are completely manufactured, installed and pre-tested in the factory and then assembled, connected and commissioned on site. This makes them fast and easy to set up. These substations are also easy to upgrade and make the best possible use of the available space. As a result, they are a time-saving and economical alternative to conventional stations built on site and are suitable for a wide range of applications.
The Very Large Telescope (VLT) array in Chile is part of the Paranal Observatory, the flagship facility for European ground-based astronomy, and it is the world's most advanced optical instrument. The VLT array consists of four unit telescopes, each with a main mirror measuring 8.2 meters in diameter, and four moving 1.8 meter auxiliary telescopes, all of which can be combined into one large array. The telescope is operated by the European Southern Observatory (ESO), the leading European organization for astronomical research.
