Taking a transformer oil sample requires using the bottom drain valve, ensuring the system is under positive pressure, cleaning the port thoroughly, and flushing 1-2 liters of oil to remove contaminants. The sample is collected into a glass syringe or bottle via tubing to prevent air bubbles, immediately sealed, and labeled for analysis.
