Plenty of good stuff thanks. There is the opportunity to increase board volts as the board is fed via a unit transformer with off load tap changer. However, this board also feeds our static started and excitation isolation transformer therefore I am reluctant to do so.
At the risk of pushing my...
Thanks for the useful advice guys.
The Board Volts are 3301V. Sorry I ommited that information in the first instance.
Through some more research it looks as though there has been modification to allow for extra flow through boiler tube leakage etc..
Just a quick question Edison, the...
Hi guys,
I have searched this subject with some success but the thread I'm after is now closed.
I have on site an Alsthom induction motor coupled to a sulzer HP boiler feed pump. The motor is running at 106% FLC and has been since 2006, I cannot look further back as there are no records. The...
I have seen this several times by either: Recessed paxeline connections rounding off or breaking during installation therefore causing looseness. Sometimes the recesses are counter bored and therfore cannot be properly tightened properly as the bolt will turn.
Secondly: Somebody didn't tighten...
Sounds like they're running 415 system and somebody has measured the supply @ 416. The power station that I work at use 415 but out supply measures at 430Vish. My previous place of work measure at around 420V.
Hi guys, I have tried searching without much luck. This, I'm sure I should know this but I'm getting a bit swamped.
I have on site a breaker feeding a 3 phase dis board. The breaker obviously has a 3 phase (100A) overload unit but also has an RCD. The RCD is fed from the secondary side of a CT...
Hey Abrar, What paper mill are you working at? I am an industry nerd lol. I worked at ayelsford mills for ten years and like to keep track of the paper industry.
P.S I assume you have checked entire circuit for health. What protection system are you susing? IQ, MM, Allenwast???
Hi thanks for your reply. Now that you have posted the reply I have found the info I was previously searching for but could not find!! Aint that a pip!
Sorry for creating a superfluous thread. Keep on trucking.
Hi all, I have tried searching without much luck so here is my question:
I was recently talking to somebody about a group of motor cables at their place of work that have been tested and showed dead shorts to earth. They are connected to 3.3kV motors that have been run without problem, they...
