The first batch of a large order of 96 isolation transformers for Data Centres is ready.
These transformers, with special features, will be inserted into a modular and scalable hyperscale architecture for a Data Centre under construction in northern Italy.
The transformers supplied will be inserted as components of a switchboard to protect the UPSs present, electrically isolating the system and protecting it against possible overvoltages, overcurrents and harmonics.
CHALLENGES FACED
- Definition of specifications in constant collaboration with the customer in order to meet the technical and performance requirements.
- Limitation of the space available for installation and consequent study for sizing the equipment.
- Maximum reduction of iron losses and no-load current typical for this type of application in which the transformer, being always powered, requires the minimisation of no-load losses.
- High short-circuit current (Vdc=10%) which required the installation of an integrated reactor of complex dimensioning and production.
- Short delivery times in relation to the required quantity.
In addition, a prototype was produced that underwent technical and functional tests (FAT) and was approved by the customer, allowing the entire order to proceed.
