We recently performed a full evaluation of our Class II, Division 1 classified locations (coal handling). There were several instances in one building where single locknuts were used for conduit penetrations in enclosures.
What can we do to meet the Code requirements for these...
My plant electricians are getting ready to replace the braided connection from our utility generator to our isolated phase bus conductor system (I.e. isophase). The voltage is 20kV.
In the past, we have used No. 2 EJC electrical joint compound at this connection. The isophase OEM rep just told...
I am looking to install several 1000W exterior lights at our facility. I have been told by the vendor that I can supply any voltage that I want and he will select the ballast accordingly. All of the 277/480 lighting panels that are nearby are fully loaded, so I am looking at feeding the lights...
Hey, I've got a 2002 Chevy Avalanche and I let my buddy borrow it to move some stuff. Well, being the nice guy that he is, he decided to fill the fuel tank up before he gave it back to me. The problem is, for some reason he thought the truck was a diesel and put about 12 gallons of diesel fuel...
I need to establish a load profile for our DC battery system at a U.S. power plant. The profile is being used to evaluate the adequacy of size of our battery system. I have two questions:
1) What is a typical estimate for DC current needed for 2400V switchgear to trip? I know that the...
We recently ran an URGE test on a steam turbine generator. We didn't experience any problems, but after reviewing some data, we realized that there is some variation in the stator currents for the different phases. We measured up to about a 3% difference between two of the phases. My question...
