The transformer oil change procedure typically involves several essential steps to ensure safety and efficiency. First, begin by determining the need for oil change through analysis of the current oil’s condition, checking parameters like moisture and acidity levels. Once you confirm the need, switch off the transformer and isolate it from the electrical supply to avoid any hazards. Next, prepare the necessary equipment, including a vacuum dehydrator, oil filtration unit, and suitable storage containers for the used oil. After establishing a safe workspace, drain the old transformer oil through a designated drain valve, ensuring that the process complies with environmental regulations for disposal. Following the complete drainage, perform a thorough cleaning of the tank to remove sediments and contaminants. Once cleaned, fill the transformer with new oil, ensuring to avoid moisture contamination during the process. After filling, conduct necessary tests on the new oil for quality assurance before reconnecting the transformer to the power supply. Finally, monitor the transformer closely after the change for any abnormalities during its operation. Adhering to this transformer oil change procedure helps maintain optimal performance and longevity of the transformers.
