1. Acid value and copper sheet corrosion rate:The acid value and copper flake corrosion rate of the insulating oil are low, which means that it is not easy to produce acidic and corrosive substances in the process of use, and has low corrosiveness to the metal parts of the equipment.
2. Environmentally friendly:Some new insulating oils such as vegetable oil-based insulating oils have better environmental performance and can be biodegradable to reduce the impact on the environment.
3. Verification Methods
(1) Visual Verification: Conducting a visual assessment of the oil's color, aroma, clarity, and other observable qualities.
(2) Physical Testing Regimen: Measuring critical physical parameters such as the oil's density, ignition points, and pourability to ensure performance standards.
(3) Chemical Composition Analysis: Examining the oil's chemical content, focusing on acidity, neutralization capability, moisture, and gas levels.
(4) Electrical Performance Evaluation: Evaluating the oil's electrical properties, specifically dielectric characteristics including loss, constant, and withstand voltage capabilities.
