9 MVA Transformer for CERN, Switzerland

Subbiano Arezzo, Italy, August 2019 – For the world’s largest and most respected centre for scientific research, Tesar supplies a 9 MVA transformer. The transformer successfully passed the short circuit test in the high power laboratory of CESI in Milan and will now be installed at CERN in Switzerland. Over the past 20 years, Tesar has supplied more than 200 transformers to the scientific research centre.

A 9 MVA transformer from Tesar will be installed at CERN, Switzerland. There, the transformer will be used to supply power to the cryogenic systems of the Large Hadron Collider accelerator to maintain the temperature of the superconductors at 1,9°K – the coolest point of the universe.

Some specifications about the project:
• 9 MVA transformer
• Custom-made design
• Dry-type cast resin filled
• Voltage ratings of 18/3.3kV
• Protection class IP33
