We have a Ross Engineering 30 KV divider.  In the realm of GOOD brand names, If I were shopping for a good 100 KV divider, what other brands are capable of similar accuracy to the Ross.  I like Ross, but in looking for possible used dividers, I need to be able to select from what is available.  Ross is definitely very good, but I want a variety of brands to choose from. Not sure h ow I feel about Hipotronics dividers.

There used to be company called Julie Research,products now produced/avaiable fom ohm labs.  As a point of trivia when I was in the Army in the mid 80s there were some issues with Julie Labs, 60 minutes ran a couple of pieces about "the Julie Affair".  The short of it was the army was buying test equipment from Fluke & Tek (no mention of HP in the stories I saw).  Julie produced a calibrator that was cheaper & supposed a good.  The Army wasn't too keen on them and since Julie was out of New York with a powerful congressional delegation they raised a stink and our modernization in TMDE was frozen while it was hashed out.

A point of trivia.  It has been way past statute of limitations, but to protect folks involved, I'll be a little vague.

I didn't work for the Fortune 100 company involved at that time, and wasn't personally involved.  But I do know from being told firsthand about that incident.  A manager I worked for testified about this, and was pretty traumatized about the whole thing.  I believe the lab I worked for a while back may have been the one that was directly involved.  I remember that manager telling me about how he had to bring the whole system into the courtroom every day when he testified, and being thoroughly grilled.  Because I don't recall particulars accurately, I won't even try.

I am familiar with JRL, have worked with some of their stuff over the years in various labs.  IT is good quality in general.  It was a shame they had the problems they did.  We even have one of their multi-tap 0.001% dividers here.

As for good AC/DC dividers, there really isn't much out there.

I remember as well, at Sacramento Army Depot e had one of the Julie systems, was much better than the other brand, seem to remember a three star got his rear handed to him

We recently bought a Vitrek 4700 high voltage meter, which will read up to 15 kV directly, and they have dividers that go to 100 kV. We use the 4700 + divider to calibrate glove testers, bucket truck testers, and other high voltage equipment, and we're pretty impressed with them. www dot vitrek dot com.
