TRENCH IOSK 362 SR Current Transformer
TRENCH IOSK 362 SR Current Transformer
(OP)
Does any one have any photos or pictures of internal guts of a TRENCH CT?
I am just trying to get an idea on how this CT actualy looks internally
Thanks

It is an oil-paper insulated CT.
What specifically do you want to know about the insides?
RE: TRENCH IOSK 362 SR Current Transformer
Also, the secondary seems to show one long rectangle with a line above it and it didn't make sense to me.
The drawing is copyrighted or else I would have posted it.
RE: TRENCH IOSK 362 SR Current Transformer
I can probably explain it to you if you choose to post it.

On the secondary schematic, the line above means that it's an iron-core, as opposed to an air-core, i.e. something like a rogowski coil.

So if my CT ratio is 200:5 does it mean that I have 160 turns in the secondary?
How are these 4 primary conductors laid out? Are they twisted together? or is it representing one conductor wraped 4 times around the core?
RE: TRENCH IOSK 362 SR Current Transformer
I'm not sure of the specifics on this design, but I assume that the conductors are aluminum 'rods', i.e. solid conductors. They would be laid out in a manner where they could be connected in series via return conductors (most likely outside conductors and the head housing) wrapping around the head.
They are not twisted, but rather for 4 independent turns around the head connected in series.
