Thanks busbar & jraef,
Yes, I had found the Trip Class 600% maximum rating in previous Google searches, too. And it explains why here at the nuclear plant we test to verify the overloads won't trip early for the safety valve motors, and why we pick the heaters for them two sizes higher than...
Thanks, Busbar. This discussion is starting to get away from my original question, but it's still interesting. We're a power generation facility and I think our techs use Doble relay test equipment to inject the test current directly into the overload heaters. The original question I asked...
At the plant where I work, we periodically test some important thermal overload heaters in place (in the MCC). I want to make sure we're doing it right, so does anybody know if there are "standard" test methods with acceptance criteria that take into account the temperature difference between...
OK, so we've explored a few different meanings for "Engineering Configuration Management" and I've learned a little about the meanings other than my own narrow experiences at a nuclear power plant. Maybe the next post will be able to pick a specific area to talk about. I remain...
It looks like different folks will have different definitions for the term "configuration management." I work at a nuclear electric generating facility. Here, Configuration Management is the process we use to keep the drawings up to date and keep the plant configuration in accordance...
