How do you check transformer oil levels?

To check transformer oil levels, first, locate the oil level gauge on the transformer, which is typically situated on the side of the tank. Ensure the transformer is de-energized and isolate it from the power supply for safety. Inspect the oil level indicator; it usually has a marked range indicating the acceptable levels. If the gauge shows the oil level below the minimum mark, this may indicate a leak or that the oil needs replenishment. Additionally, you can visually inspect for signs of leaks around the joints and seals. It’s also crucial to perform regular sampling and analysis of the oil to assess its quality and confirm that it meets required specifications. This thorough evaluation will help ensure the proper functioning of the transformer and prevent operational issues. Remember to consult the manufacturer’s guidelines for specific instructions related to your equipment. By understanding how to check transformer oil levels properly, you can maintain the longevity and efficiency of your transformers.
