Metal Enclosed Electrical Bus, The Lifeline to the Transformer, What You Should Know and Why It’s Important to Your Bottom Line

Brief Summary:
The purpose of this article is to educate power plant operators and maintenance personnel on the importance of metal enclosed electrical bus, an often-overlooked system critical component spanning from the generator to the main transformer, carrying the system’s full current. Metal enclosed bus is stand-alone, custom made for each plant, and non-redundant. When a failure occurs; the entire energy producing system shuts down until this critical component and its appendices are repaired or...
