What are the transformer oil analysis labs used for in power transformers?

Transformer oil analysis labs are used for in power transformers to evaluate the condition and performance of the insulating oil. These labs conduct tests to measure parameters such as moisture content, acidity, dissolved gases, and dielectric strength. By analyzing these factors, the labs can identify potential issues like insulation degradation or overheating, enabling proactive maintenance and ensuring the reliability and longevity of the power transformers.
