Westinghouse Info
(OP)
Hi all:
Does anyone know where I can find original info on Westinghouse KX-642 / KR85? I found a general description on a museum website which tells me it is a voltage arrestor. I need to replace several of these and would be more comfortable if I knew what the original specs were.
Thanks,

RE: Westinghouse Info
Did you offer to sell them to the museum? After all, what good museum dosen't have a KX-642?
RE: Westinghouse Info
These are conncected across the terminals of a CT circuit where the CT is on the neutral of a 72 kV cap bank. There are also 2 terminals tied to the 72 kV neutral. Our dwg refers to it as an "arc tube", though I believe it is essentially a surge suppressor.
I get nervous offering stuff to a museum when it's 18 yrs younger than I am!
RE: Westinghouse Info
I have heard about arc-tube's, but I don't know the difference between them and an arrester. However if the CT's are not of a high voltage design, it could make since. But then again it may have some impedance to force some of the current through the CT.
ABB I thought purchased much of the Westinghouse power division, so you might check with them (warning the web site is hard to follow).
The CT on the nutral of a capacitor bank is used to detect unbalance, so I don't think they would want to completly short it out with an arrester. Again it might be for spike protection of the CT.
The part number (like most) don't have a meaning. A description is much better.

Anyway, much appreciated that.
