At the beating heart of the digital economy, data centres are the foundation on which the entire global information ecosystem rests. In these facilities, where every millisecond matters and every interruption can lead to significant losses, power management is not merely a technical necessity, but a strategic priority.
In this context, transformers for data centres play an essential role because they contribute to power quality, the electrical isolation of loads and the overall stability of the installation.
For a major data centre project for one of the world’s leading IT groups, Ortea supplied 13 three-phase isolation transformers rated at 75 kVA, designed for critical applications where reliability, adaptability to grid conditions and temperature control are decisive factors.
THE ROLE OF TRANSFORMERS IN DATA CENTRES
A data centre is a high-load-density environment in which servers, IT equipment, cooling systems, UPS units and switchboards must operate with maximum reliability. In this architecture, the transformer does not simply transform voltage, but performs crucial tasks for the operational continuity of the infrastructure.
Its main functions include:
- protection of sensitive loads, thanks to the galvanic isolation of servers and network equipment;
- management of power quality, helping to reduce electrical noise and protect hardware from disturbances and voltage spikes;
- stability of power distribution, which is essential in environments operating 24 hours a day, 7 days a week.
In data centres, transformers are important because they help manage non-linear loads, which are typical of IT environments, and provide greater adaptability to supply grid conditions.
In an infrastructure where any downtime can have significant economic and operational consequences, choosing transformers designed for critical applications means reducing risk and increasing the resilience of the entire system.
DESIGNING FOR OPERATIONAL CONTINUITY: THE FEATURES OF THE SUPPLY
Ortea’s supply for this project in the Far East does not concern standard components, but transformers designed to meet the needs of a mission-critical site. The construction specifications highlight an approach focused on operational continuity, monitorability and application robustness.
ADAPTABILITY AND VOLTAGE FLEXIBILITY
One of the strengths of the supply is the presence of tappings on the primary side (±2 x 2.5%). This configuration makes it possible to adapt the transformer to different input voltages, ensuring that the output remains stable at 415 V even when there are fluctuations in the supply grid. In a data centre, this flexibility is important in maintaining the correct power supply to critical loads and supporting operational continuity even in less-than-perfect grid conditions.
ADVANCED THERMAL MANAGEMENT
To prevent overheating and ensure a long service life for the components, the transformers are equipped with a dedicated thermal management system. In particular, the supply includes:
- extraction fans positioned on the side panels to optimise airflow;
- 3 PT100 thermal probes for each unit, connected to a temperature control unit.
This system makes it possible to report and identify any thermal anomalies promptly, allowing preventive action before overheating becomes an operational issue. In critical sites, temperature monitoring is one of the most important activities for preventing failures and protecting service continuity.
ROBUSTNESS, SHIELDING AND MECHANICAL PROTECTION
The design of the supply was developed for demanding industrial and technological environments. Each transformer incorporates a range of features that improve safety, stability and operating performance.
These include:
- 4 anti-seismic/anti-vibration pads for each unit, helping to reduce mechanical noise and protect the structure;
- double electrostatic shielding between primary and secondary, earthed, for greater attenuation of electromagnetic interference;
- insulation class H, designed to withstand high temperatures up to 180°C, even under heavy load conditions.
These elements reinforce the suitability of the machine for applications where power stability, interference reduction and protection of connected equipment are central requirements.
ORTEA CASE STUDY: 13 THREE-PHASE ISOLATION TRANSFORMERS RATED AT 75 KVA FOR A DATA CENTRE IN THE FAR EAST
The project represents a concrete proof point of Ortea’s ability to operate in highly critical environments. The contract involved the supply of 13 three-phase isolation transformers rated at 75 kVA for a major data centre project in Singapore, intended for one of the world’s leading IT groups.
The value of the supply lies not only in the quantity involved, but above all in the combination of technical customisation, attention to construction details and solutions designed to ensure stable power supply and long-term operational reliability. For this reason, the contract confirms Ortea’s ability to operate as a reliable partner for mission-critical infrastructures, where operational continuity is a design requirement rather than simply a performance objective.
ORTEA, A RELIABLE PARTNER FOR CRITICAL INFRASTRUCTURES
When it comes to data centres, the quality of the component is important, but on its own it is not enough. Project expertise, reliability of supply and the ability to meet the specific needs of applications that cannot afford interruptions are also required.
In this respect, the contract described highlights an approach based on concrete specifications: voltage adaptability, thermal control, shielding, mechanical robustness and attention to power stability. It is through these technical aspects, rather than through promotional claims, that Ortea’s positioning as a solid partner for highly critical electrical infrastructures emerges.
FAQ ON TRANSFORMERS FOR DATA CENTRES
WHAT IS A TRANSFORMER USED FOR IN A DATA CENTRE?
A transformer in a data centre is used to electrically isolate loads, adapt voltage levels, support power quality and contribute to the operational continuity of the infrastructure.
WHY IS K-FACTOR IMPORTANT IN DATA CENTRES?
Because data centres supply many non-linear loads, such as UPS systems, servers and switching power supplies, which can generate harmonics. A transformer with an appropriate K-Factor is designed to handle this type of electrical stress more effectively.
WHAT IS THE ADVANTAGE OF MULTIPLE TAPPINGS ON A TRANSFORMER?
Multiple tappings allow the transformer to be adapted to the conditions of the incoming grid and to optimise the electrical behaviour of the application. In data centres, this helps maintain the correct power supply to critical loads.
WHY IS TEMPERATURE CONTROL SO IMPORTANT?
Because overheating is one of the conditions that must be monitored most carefully in critical sites. Probes and control units make it possible to detect thermal anomalies in advance and take action before they become an operational problem.
WHAT ARE FANS USED FOR IN TRANSFORMERS FOR DATA CENTRES?
Fans help improve heat dissipation and keep the machine within its design thermal limits, especially in environments with continuous loads and demanding operating conditions.
ARE ANTI-VIBRATION SUPPORTS REALLY USEFUL?
Yes. Anti-vibration supports improve the mechanical stability of the equipment and help reduce the stresses transmitted to the installation environment.
WHY CHOOSE ORTEA FOR A SUPPLY INTENDED FOR A DATA CENTRE?
Because in data centres it is not only the product that matters, but also the reliability of the partner. Ortea can support projects for critical sites with robust, monitorable technical solutions designed for applications where operational continuity is essential.
