we had a site visit the other week by a sales rep and an engineer of a company wanting to sell us a 'voltage optimisation unit' for the factory. They have today sent me through a proposal. They have contacted our electrical supplier, and obtained our site voltage profile for the last year. What they propose to do, is to instal this unit which will reduce our voltage from 253V-239V, down to 220V minimum. Their proposal is all in single phase terms, and our site is mainly made up of 3 phase induction motors, so i have asked them the to re-do the the proposal in more relevent terms to us.
My question...
I can understand their sales pitch of lower stable voltage, less cost on utility bill (they guarantee a saving of 9.2% per annum), but i don't know that much more about it. Has anyone else adapted any such method, or had any experience in this sort of thing?
We are not considering this with any great intent (yet) as my worry is the effect of lowering the voltage too much for some of our site to function, a problem that realistically wouldn't come to light until commisioning. That alone is putting me off as our plant has areas which are VERY old machinery.
thanks for reading my ramblings...
