What are the steps for installing a high voltage transformer bushing?

Installation involves several key steps: preparing the transformer, ensuring the bushing is free of contaminants, and aligning it properly. The bushing is then inserted into the transformer’s tank, and electrical connections are made. Proper sealing to prevent oil leaks is critical, followed by insulation resistance tests and checking for mechanical stability. Finally, the bushing is monitored during initial operation for temperature changes and leaks.
