If there is faulty in the system, the transformer probably won't stay on very long - the magic smoke will all leak out.

Hopefully your protective devices (fuses or circuit breakers) will do their job quickly to try to prevent this from happening. If the transformer works for longer than the protection trip times (without a trip), it's probably okay. What does your commissioning spec say?

Forever, or until the service life of the conductors has elapsed.

For 33kV it will monitor about 60 days

For 22kV it will monitor about 40 days

For 6.6kV it will explode immediatly after it was put on and the devil will come and take it for his fires
