Hey,
Can anyone tell me where I could find a patent for a Cast-Resin Transformer, first invented by AEG in Germany in 1965?
I have found this website: http://www.dpma.de/english/patent/index.html however it doesn't appear to be that useful.
Any help would be appreciated,
Thanks.
Hey,
I'm attempting to redesign a switch and the new design in supposed to encorporate contactors in series with fuses. However, one of the requirements is for no contact welding to occur. The rated surrent has been calculated as 2405A and the maximum fault current is 40kA.
So I understand...
Well no need to be too alarmed, I'm just finished my third year of college and have been working for just over a month- so I have very little experience with this stuff! Also I'm pretty sure that my boss is aware of this too...
Brilliant guys, thanks a lot- i'm learning more here than I have over the last 3 weeks researching this thing!
However, I have just been told that it is necessary for the new switch to be capable of carrying out regular switching automatically- i.e. not via a handle. Hence, as far as I can...
Okay, firstly let me clarify a few things that I should have mentioned at the start. I am working in Germany at the moment, not the US. Also, the standards that I have been using refering to throughout this project are IEC as this is what my boss wanted. The person that I have been in contact...
It's a low voltage network (a crane infeeder, after the voltage has been stepped down). The vlotage on the secondary of the infeed transformer is 480V.
Also I think that a switch- disconnector has to be used for this project, as one of my contacts has stated this-however I am trying to find...
I've been trying to research this all day but I can't find any website that states the differences between disconnectors and switch- disconnectors. From what i've gathered, a disconnector is incapable of making/breaking current and is only used for the purpose of isolation, once the current in...
Is a switch- disconnector just another name for a disconnect switch?
Are these circuit elements operated manually (by hand)?
If regular switching is required in the circuit, will it be necessary to also incorporate contactors in series?
Thanks,
Mark
