Re: [TCML] Turn-to-Turn short circuit

["Christoph Bohr" <cb@xxxxxxxxxxxxxxx>]

Hello Matthew.

I followed this thread ober the last days, here are my 2 cents:

1.: the wire looks to me, like the stuff you use around the garden or
for flowers and the like.... correct me if I'm wrong. If the green coating
is just dark green and not very thick its probably the stuff I am talking about.
Geen enamel wire is usually pretty shiny and sort of a transparent green which
should be relatively resistant to scrathing...

2.: As the overlapping turns are at the very end, it would have probable been
less work to correct the problem than to type the posting ;-) ... sorry, so offense
intended...

3.: If you are using the coils is some sort of protection device for an NST or
similar,
the now common practice would be to use large resistors.
Theoretically chokes might be the better component to give you a LC over a RC
network, if you know very well what you are doing. If not, they might induce more
problems than they solve. Again, as others said and apart from all the nice LC filter
math,
if the device is physically to small to withstand the whole expected voltage across
it in
the case of failure it was designed for, it will be useless.....

4.: Yes, it might be better to use different wire. Documented is nice, but at least
something you rougly know what it can do or was designed for.
ebay or local motor shop for new stuff of even unwinding transformers for smaller
amounts on a low budget...
Otoh ... normal insulated wire works just as well for your purpose I believe....

Good luck in building whatever you are building ...

regards

Christoph Bohr
