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.

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.

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".

But triggered by the first fault, no? If the first fault hadn't
occured, neither would the second one (at that particular time).

I guess it all depeneds on how you want to define the chain of
cause-and-effect...
