I recall hearing a story about a tech who was working in a small hydro
generating plant who had found that a voltage transformer used to feed the
local synchronizing relay had been connected 180° out of phase since the
plant was built. He fixed the connection, then stuck around to watch the
next synchronization. The generator breaker closed, then the local
electrician said "Hey, what's wrong?  Where's the huge bang?"
