Super Bowl Blackout Caused By Defective Protective Relay 210
New submitter wilby writes "Power company Entergy New Orleans says the Super Bowl blackout was caused by device designed to prevent power outages. A device designed to improve the Superdome electrical system reliability instead caused it to shut down dramatically during Super Bowl 47. [The company] said testing traced the source of the problem to an 'electrical relay device' it had installed in December to protect Superdome equipment in case a cable failure occurred between the company's switchgear and the stadium."

You sir, are a bit of an ass. He is giving relevant and interesting information, which is true. I know, I'm also a process control engineer. The protection relay is quite a complex device (normally approaching the complexity of a small PLC) and very easy to set up wrong.
