How is transformer oil analysis guide performed and what information does it provide?

Transformer oil analysis is performed by collecting oil samples from the transformer and subjecting them to various tests, including dissolved gas analysis (DGA), moisture content measurement, and furan analysis. This process provides critical information regarding the condition of the transformer, such as insulation degradation, potential faults, and overall health. By interpreting the results, technicians can predict failures, assess maintenance needs, and extend the transformer’s operational lifespan.
