What are the technical aspects of transformer oil contamination?

Transformer oil contamination can significantly impact the performance and lifespan of power transformers. Key technical aspects include the presence of moisture, which reduces dielectric strength, and particulate matter, which can cause short circuits. Chemical contaminants, such as acids or dissolved gases, can lead to accelerated aging of insulation materials. Regular testing for these contaminants, along with proper filtration and maintenance practices, is essential to ensure the reliability and efficiency of transformer operations.
