Relay test equipment
(OP)
Our company is in the process of looking for a new relay test set. Does anyone have any suggestions? We are reviewing the
Megger MPRT, KoCos ARTES 440 II, Omicron and Doble 6100. We have experience with the Doble 2200 series of test sets but would like to move away from them.
Any suggestions would be helpful.

The newer test sets source as many as 4 voltages and 6 currents at the same time. (in one convenient package). For field testing portability is a major concern. The newer test sets are also lighter (helps reduce the potential for injury while carrying the equipment).

I have not used many testers except Manta, Omicron, and Doble. For relay testing, Omicron beats all of the above hands down.
FYI - there is some software that recently came out that can be used with a bunch of testers. This allows one software package to be used for multiple testers. This is something worthwhile if your company uses different test sets but only wants to use one software package to reduce the number of test sequences needing programmed into different test sets. Write one test program for any test set.

We also have an Omicron Relay Test set and Personally I don't really like it. It seems harder to set up and the tests arn't as easy to automate like with the doble. They do put out a much better looking report though.
My vote is definatley for the Doble 6150! After I got good with this test set I could easily test up to 4 involved SEL relays in 10 hours (351s and the like).

Seems like a pretty good unit. It has enough VA to do a KD-10 set at 0.3 ohms reach. No problem.
Does anyone really use 6 currents for relay testing? If so how often?

Remember when you actually calibrated relays, slaving over a hot load box. Ahh, those were the days. By the way, hi David Beach, its Mike Young, how's life in the big city.

Once you have it boiled down to 2 or 3 vendors ask them to send an application engineer (not a sales rep) to demo the unit, and ask them if you can keep it for a few weeks to try it out. Most of the companies have demos for just such things.
RE: Relay test equipment
Just as mikey70 suggested we invited application engineers to demo their units. The litmus test was a Beckwith 3420 generator relay and a KD-10 with a reach of 0.31 ohms. The Manta unit handled everything wonderfully.
The Manta unit proved to cover all the bases we need.
I would like to thank everyone for the input.

keep your eye here for SR51 or 76. http://www.govliquidation.com/index.html
Bought one about 1 year ago and it cost more to ship from CA than I paid for it. When I it arrived the original leads (and orignal rubberbands I believe) were in it.
Just like Ebay, hit and miss, but not as much bid competition.
