Typical transformer oil analysis results often include key indicators such as moisture content, dissolved gas analysis (DGA) results, acidity levels, interfacial tension, dielectric strength, and the presence of particulate matter. Moisture is usually assessed in parts per million (ppm), where lower values indicate better insulation performance. DGA reveals the concentration of gases like hydrogen, methane, and ethane, which can indicate overheating or arcing within the transformer. Acidity levels are checked; a rise can signal oil degradation or contamination. Interfacial tension can indicate the presence of contaminants, and dielectric strength is crucial for assessing the insulating properties of the oil. Overall, thorough transformer oil analysis results help in monitoring the health of transformers, ensuring reliability, and planning for maintenance or oil regeneration when necessary.
