I know this is mostly American forum but I don’t know where else to put this post. For a long time it's bothering me why it is called "DIAZED" fuse. Is it some German word or what? Does anybody know the explanation? Thank you all.
Suppose your transformer originally had two separate windings (it’s not an autotransformer). Then if you connect one terminal of primary winding with one terminal of secondary with a resistor nothing will happened because there is no path for resistor current to run back. So it’s the same state...
Of course. There is an old system (at least 80 years) where lever pulls up brush holders and simultaneously push copper cylinder on slip rings.Construction is only mechanical and we can say trivial.
About busbar comment..cbarn24050 is right, when you have higher frequency in transformer you have less iron but still large induced voltage. So you can reduce number of winding turns, which means less copper.
You’re right that if you put higher than 12 V (actually about 13 V) onto the battery it would charge, but if you put too large voltage (say 15-16 V) the electrolyte will boil! So you gotta have some voltage regulation. That can be achieved by setting rotor speed or by setting field current of...
I’m not quite clear about three-phase connections that are in use. For example: in Europe is in use 63 MVA, 110/35/10 kV, YNyn0d5 three-phase transformer with both neutral points grounded. I assume that magnetic core has three legs (I didn’t actually saw it so I’m not sure). The 35 kV network is...
It's well known that the typical value of induction motor short-circuit current is about six times rated current. My question is: "Is there a typical value for synchronous generator steady-state symmetrical short-circuit current, like 1.5, 3 or 6 times rated current?" I made next...
