Installation requirements for dry-type distribution transformers
Ventilation and Cooling:
Dry-type transformers rely on natural or forced air cooling to dissipate the heat generated during operation. Proper ventilation and airflow around the transformer are essential to prevent overheating and maintain optimal efficiency.
Environmental Considerations:
Dry-type transformers are less susceptible to environmental factors than oil-immersed transformers, but certain environmental conditions still need to be taken into account.
The installation site should have protection against exposure to moisture, dust, corrosive agents, or other contaminants that could potentially degrade the transformer's insulation and components.
In harsh environments, such as coastal areas or industrial settings, additional protection measures, such as weatherproof enclosures or specialized coatings, may be necessary.
Electrical Connections and Grounding:
Proper electrical connections, including the primary and secondary windings, as well as the grounding of the transformer, must be carried out according to relevant electrical codes and manufacturer's specifications.
