Another Short Question

Hi Everyone, 

I have another relatively short question. After reading a little about DC 
coils, I started to wonder: What are the advantages of powering a coil with 
DC? At first thought, I believe that DC would offer the capacitor a smoother 
charging source, possibly increasing the lifespan of the cap. I'm not quite 
sure about this one, but it would also seem as though a RSG would not have to 
be salient-pole synchronous because there would be no peaks or zero crossing 
points or anything like that so one could use an 1800 RPM motor without 
having to modify it. A more specific question I have is how the DC would 
affect the level of capacitance for the cap. since frequency of the incoming 
line is a factor involved in calculating the capacitance and therefore the 
resonant frequency of the primary LC circuit. In relation to my previous post 
(thanks for all the replies :-)), I have decided that I am going to start 
hunting for a suitable <use! d&!
gt; transformer tomorrow. I have also thought about 
depotting it right off the bat, since I have heard that NSTs run cooler when 
depotted and maintenance would be much faster should something fail. I was 
thinking that I could use the freeze and chip method to a certain extent, 
before I have reached the core and windings, and then use a solvent like 
mineral spirits, kerosene, or gasoline to remove the rest of whatever that 
stuff is (tar, asphalt... i'm confused...). Well, I guess that will be all 
(for now :-) Thanks ahead of time.
