Introduction: Why Choosing the Right Transformer Type Matters Transformers are vital components in any electrical system, stepping voltages up or down to meet power distribution needs. Choosing between an oil-filled and a dry-type transformer isn’t just a technical decision—it directly impacts safety, installation conditions, long-term maintenance, and overall project cost. Whether you’re designing for a commercial building, an industrial facility, or a utility grid, understanding the key differences is crucial. What Is a Dry-Type Transformer? A dry-type transformer is air-cooled and uses solid insulation rather than oil. The windings are typically cast in resin or sealed in vacuum pressure impregnation (VPI) systems to protect against moisture, dust, and contaminants. Features: […]
