A transformer oil color chart is interpreted by comparing the oil’s color against standardized samples to assess its condition. The color indicates the presence of contaminants, oxidation, or degradation. Typically, lighter shades suggest better quality, while darker hues may signal issues like moisture or thermal breakdown. Regular monitoring using the color chart helps in preventive maintenance, ensuring the transformer operates efficiently and prolonging its lifespan.
