Testing a motor for durability: how we test dynamic UPSs

Hello, Habr! My name is Victor, I am the chief power engineer at the Udomlya mega-data center. My colleagues have already shown how we organize a guaranteed power supply to the data center using diesel generators and regularly check their performance . But besides the diesel generator set, there is other equipment that can simultaneously provide guaranteed power supply and uninterruptible power supply. We are talking about diesel dynamic UPS (DIBP). Such installations are in our mega-data center, and we have already talked a little about their device in a tour of the data center .





Today I will show you how we test DIBP diesel engines to be sure of their reliability.





A little about the device DIBP
