THE CUSTOMER
The customer is a company involved in the implementation of Data Centres.
THE NEED
The customer needed to insert a series of isolation transformers, with precise technical and dimensional characteristics, into a modular and scalable hyperscale architecture for a Data Centre under construction in northern Italy.
The transformers were to be inserted as components of a switchboard to protect the UPSs present, electrically isolating the system and protecting it against possible overvoltages, overcurrents and current harmonics.
OUR SOLUTION
The challenges faced and solved by Ortea were:
- 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.
The series of isolating transformers specifically designed and manufactured for this order has the following main technical characteristics:
- Nominal Power: 800kVA
- Frequency: 50Hz
- Vector group: Dzn0
- Input voltage: 400V
- Output voltage: 400V @50% load
- Primary side sockets: ±5%
- K factor: 9
- Short-circuit voltage (Vcc%): 10%
- Insulation class: H
With this supply, Ortea once again demonstrates its production and design capabilities by pursuing the end customer’s needs and supporting them during all phases of project implementation.
