What should be done if a pad-mounted transformer is leaking oil?

If a pad-mounted transformer is leaking oil, it is crucial to address the issue promptly to prevent environmental damage and ensure operational safety. First, identify the source of the leak and assess the situation to determine the amount of oil escaped and the potential effects on surrounding areas. Next, contain the leak by using absorbent materials or booms to prevent further spread, especially if the oil is transformer oil, which can contain harmful substances. It is important to check the level of oxygen in transformer oil as it can affect insulating properties and lead to further degradation. After containing the leak, notify the appropriate environmental or utility authorities as required and arrange for a qualified technician to repair the leak. It is also essential to inspect the integrity of the transformer to prevent future occurrences and ensure proper maintenance routines are followed, which may include regular checks for oxygen in transformer oil levels to mitigate risks associated with oil degradation.
