Cryptocurrency has taught me to love math and at the same time be baffled by it.

Conclusion: Based on this engineer’s training, education, experience, and available evidence, in
the context of the investigation that was performed, this engineer has developed the following
conclusions to a reasonable degree of engineering certainty:
1. The cause of the power outage was a misoperation of the relay.
2. A contributing factor to the misoperation of the relay was the unstable operating condition
of the relay around the setpoint of the subject relay due to a design defect.
3. A contributing factor of the outage was the inappropriate current trip level setting of the
relay, which was the factory default value.
4. A contributing factor to the inappropriate setting was inadequate communication between
the manufacturer and the utility.
The opinions and conclusions expressed in this report are based on the information available to
the engineer as of the date of this report. If additional information becomes available that
affects these opinions and conclusions, this engineer reserves the right to supplement this
report.


I would really hate to be responsible for any part of this mess.
