Quality Requirements: Transformer oils must meet strict industry standards such as ASTM (American Society for Testing and Materials) and IEC (International Electrotechnical Commission) standards. These standards dictate parameters like viscosity, flash point, pour point, acidity, and dielectric strength.
Maintenance and Testing: Regular testing of transformer oil is essential to ensure its continued effectiveness. Tests include checking for moisture content, dissolved gas analysis (which can indicate potential faults), and monitoring the oil's chemical and physical properties.
Replacement and Recycling: Over time, transformer oil may degrade or become contaminated, requiring it to be replaced. Used oil can often be regenerated or recycled, undergoing processes to remove impurities and restore its properties.
