Isolation transformers play a crucial role in the data centre electrical system, acting as essential components that facilitate the efficient and reliable distribution of power.
VOLTAGE ADJUSTMENT
One of the main functions of isolation transformers in data centres is to increase or decrease the voltage of incoming electrical energy as needed. This is important because different types of equipment and machinery within the data centre may require different voltage levels to operate effectively. By adjusting the voltage level accordingly, transformers allow different electrical devices to be integrated into the data centre’s energy infrastructure.
ISOLATION AND PROTECTION
In addition to voltage conversion, transformers also play a key role in isolating electrical circuits and protecting against surges and fluctuations. By isolating the different parts of the electrical system, transformers help prevent the spread of electrical disturbances and minimise the impact of any faults or malfunctions. In addition, transformers with protective functions such as surge suppression and voltage regulation contribute to the overall stability and resilience of the data centre’s power supply.
WIND, PHOTOVOLTAIC AND BESS SYSTEMS
A further strategic role of the isolation transformer is to serve BESS (Battery Energy Storage System) and renewable energy systems (wind, photovoltaic, hydrogen), which include inverters, batteries and distribution cabinets. These systems allow the energy produced to be stored and made available when needed. Between these energy storage systems and the main grid, galvanic isolation of the two circuits is appropriate in order to protect the inverter and batteries from any overvoltages and/or surges generated in the grid. Furthermore, in BESS systems, the transformer performs the function of adapting the voltage of the renewables (400V) to the operating voltage of the BESS system (typically 690V-480V).
SAFETY FOR UPS IN DATA CENTRES
Another important aspect of transformers in data centres is their role in supporting emergency power systems. Many data centres use uninterruptible power systems (UPS) to ensure continuous operation in the event of a power failure. Transformers, an integrated component in these UPS systems, help to regulate and distribute power from backup sources, such as batteries or generators, to critical loads within the data centre. This capability is essential for maintaining uninterrupted operation of essential IT infrastructure and preventing data loss or downtime during power outages.
DIFFERENT ISOLATION TRANSFORMER CONFIGURATIONS
In addition, transformers can be configured in redundant or parallel arrangements to provide backup and redundancy for critical power distribution paths, further enhancing the resilience of the data centre’s electrical system.
THE CRUCIAL ROLE OF ISOLATION TRANSFORMERS IN DATA CENTRES
In conclusion, transformers play a crucial role in data centre electrical systems, providing voltage transformation, isolation and protection for the facility’s electrical infrastructure.
