Finally! Confirmation that the two faults were indeed related. As some
of us insisted (against solid opposition) from the start.

Not quite true. You conveniently snipped the *real* reason, which was
almost certainly human error.

"According to the report, the second fault occurred because automatic
protection equipment shut off the power thinking there was a fault with
the supply, because of the action taken to compensate for the defective
transformer. The report adds that this occurred because "an incorrect
protection relay was installed when old equipment was replaced in 2001".

The second 'fault' seems to have been a protection malfunction.

The key phrase is perfectly clear and obvious, at least to anyone with a
knowledge of the industry - "an incorrect protection relay was installed
when old equipment was replaced in 2001".
