I have only had one of these done and I would like to know what you consider the minimum deliverables that you would want. We just got a paper report and the labels but I thought we should have received the electronics files from the analysis as well. Is that unreasonable? The next time I asked...
Customer has a building currently fed by a single 2500kva transformer. They planned ahead for load increase and there is a pad for a second 2500kva transformer. These are connected to the dual feed utility on the primary side with S&C switches with the PMH-9 connections, one source transfer and...
I am designing power distribution on my first semiconductor fab. The building was purchased from another manufacturer and the engineer for that company specified 200% neutrals, K13 transformers and both isolated and non-isolated ground wires to the panels in the fab areas. The current owner is...
I ran into some industrial saws that I think are not properly wired. It has a transformer wired for 480 volt primary and a 240 secondary and that is all well and good. However some of the controls on the inside use 120 volt coils and there is no connection to x2-x3 on the secondary so they have...
Hi, to start my degree is in micro electronics so power distribution isn't my strong suit despite working through college as a journeyman. The journeyman stuff was why I have been asked to look into this.
Anyway, on the 480 volt power to some of our crystal furnaces we have some regularly...
