Using transformers is an effective solution for addressing harmonics in a data center. Harmonics can arise from non-linear loads, such as computer power supplies and electronic devices, which draw current in a non-sinusoidal manner. This can lead to distortion in the power system, causing overheating and inefficiencies in equipment.

Transformers, particularly those designed to handle harmonic distortion, can help mitigate these issues by isolating the harmonic-producing loads from the main power supply. They can be specially designed (like multi-winding transformers or harmonic mitigating transformers) to reduce the effects of harmonics, maintaining better power quality throughout the data center. By reducing harmonic currents, transformers help improve the overall efficiency and reliability of the electrical system, which is crucial for the sensitive equipment housed in a data center.

In contrast, increasing load on circuits, shortening cables, or minimizing equipment usage would not effectively address the root causes of harmonic distortion. Instead, these actions could potentially exacerbate the issues or lead to further inefficiencies and risks within the data center's electrical infrastructure.
