What kind of test to be conducted for transformer oil and what is significant out gases

Question

Accepted Answer

Transformer oil should be tested for dielectric strength, acidity, water content, and dissolved gas analysis. Significant out gases include methane, ethylene, and acetylene.

Dielectric strength test measures the ability of the oil to withstand electric stress without breaking down.
Acidity test determines the level of acidic compounds present in the oil, which can degrade insulation.
Water content test checks for moisture that can reduce the dielectric strength of the oil.
Dissolved gas analysis identifies gases such as methane, ethylene, and acetylene, which are significant indicators of potential faults in the transformer.
Monitoring the levels of these gases can help predict and prevent transformer failures.
