My friends at HVB-AE Power Systems always come up with something to get my attention. I stopped by today and talked with Stephanie Hayden. We have known each other for many years and it is always great to visit with her. The theme of their booth is the evolution of the gas circuit breaker.
I am a history buff and this was fascinating, but more so was where we are going next. Ask them about the gasless power circuit breaker. I think it should prove interesting.
