The furan test for transformer oil is conducted by extracting furan compounds from the oil using a suitable solvent, typically after the oil is heated and pressure is applied to ensure proper extraction. The oil sample is filtered to remove particulates, followed by a chromatographic analysis, often using high-performance liquid chromatography (HPLC), to quantify the furan content. The presence and concentration of furan compounds in transformer oil indicate insulation degradation as they are byproducts of cellulose insulation breakdown. Regular furan testing is vital for assessing the health and longevity of transformers, allowing for preventive maintenance actions to be taken before critical failures occur. Ensuring the proper execution of the furan test is essential for accurate diagnostics and the effective management of transformer oil quality.
