What are the clearance requirements for oil-filled transformers?

The oil-filled transformer clearance requirements are essential for ensuring safety and operational efficiency. Clearances are generally dictated by local electrical codes and standards, with factors including the transformer’s voltage rating, size, and installation environment being key considerations. Typically, horizontal clearances from the transformer to structures or other equipment are often required to be at least 3 feet, while vertical clearances can vary based on the transformer height. Additionally, clearances should allow for proper ventilation and access for maintenance while adhering to fire safety regulations. When installing transformers, it’s crucial to consider disturbing flammable materials and also ensure compliance with local environmental regulations related to oil spills or leaks. Always refer to manufacturer specifications and applicable standards for precise clearance requirements based on specific transformer models.
