What is the process for hv transformer oil sampling in power transformers?

The process for HV transformer oil sampling in power transformers involves several key steps. First, ensure the transformer is de-energized and properly grounded. Use a clean, dry sampling device to extract oil from the designated sampling point, typically located near the top of the tank. Collect the oil in a clean, labeled container, ensuring minimal contamination. Finally, seal the container and send it to a laboratory for analysis to assess the oil’s condition and quality.
