Dry-type transformers for data centers as the preferred technology for data centers
dry-type cast resin transformers can be suitable for data center applications, depending on the specific requirements and constraints of the data center environment. Dry-type transformers offer several advantages that make them a viable choice for certain data center setups:
Safety and Environmental Considerations:
Dry-type power transformers use air or resin as an insulating medium instead of oil, making them a safer and more environmentally friendly option. In data centers, where safety and environmental concerns are paramount, the absence of flammable oil is a significant advantage.
Reduced Fire Risk:
The absence of flammable liquids in dry-type transformers reduces the risk of fire, which is a critical consideration in data centers where the protection of sensitive electronic equipment is essential.
Ease of Installation:
Dry-type transformers are generally easier to install and require less maintenance compared to oil-filled transformers. This can be advantageous in data centers where minimizing downtime and optimizing installation efficiency are priorities.
Indoor Installation:
Dry-type transformers are suitable for indoor installations, which aligns well with the typical placement of transformers within data center facilities. The absence of oil eliminates concerns related to oil containment and potential environmental hazards.
Harmonic Mitigation:
As mentioned in the earlier response, dry-type transformers can be designed to withstand high levels of harmonics and non-linear loads. This is particularly relevant in data centers where electronic equipment can introduce harmonic distortions into the power system.
From transformers for primary power supply for utility grids to secondary units in substations, Varelen technology and innovation help increase the reliability and improve the operations of data centers while reducing life cycle cost and environmental impact.
