Dry-type transformers are the main option for indoor applications, from data centers to commercial buildings to hospitals, due to their fire-resistant design, low maintenance requirements, and environmental safety.
Just like any other electrical equipment and transformers, the life of dry-type transformers is highly dependent on proper installation, selection and regular maintenance. By following these proactive maintenance strategies, you can extend the life of your transformer and avoid costly downtime.
We have explained how to maximize the life of your dry-type transformer:
Choosing the Right Transformer
You should make sure that the kVA rating of the transformer exceeds your peak load by 20-25% to avoid overheating. Especially if you are looking for a long-lasting transformer, you should opt for robust insulation systems such as VPI or resin.
You also need to confirm the transformer’s temperature rise rating with your facility’s environmental conditions to prevent overheating.
Inspect Your Transformer Regularly
Dry-type transformers rely on air or resin insulation, which must be inspected regularly for cracks, dust buildup, or discharges. You should also use thermal imaging to detect any hot spots caused by corroded or loose windings.
Maintain Optimal Operating Conditions
Transformers usually operate under high stress due to electrical voltages. It is important to provide adequate ventilation and keep ambient temperatures below recommended levels to prevent overheating.
Moisture also reduces the dielectric strength. If necessary, it is recommended that dehumidifiers be used to control ambient humidity. It is also recommended that vents and windings be cleaned every 3 to 6 months to prevent airflow blockage.
