What are the quality parameters of insulating oil?

The quality parameters of insulating oil include dielectric strength, moisture content, acidity, and dissolved gas analysis. Dielectric strength measures the oil’s ability to resist electrical breakdown, while moisture content indicates the presence of water, which can degrade performance. Acidity levels reflect the oil’s degradation over time, and dissolved gas analysis helps identify potential faults within the transformer. Maintaining these parameters is crucial for ensuring the reliability and longevity of power transformers.
