Thanks for all the response. We have settled on the Manta MTS-5000. 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...

Valid points indeed. What type of test set do you use?

From your experience is it faster to use 6 currents or just test single phase?

More often than not I find myself paralleling the 6 currents into a more useful 3 current arrangement. I agree with davidbeach's comment but it is not mandatory.

Has anyone had any experience with the new MANTA MTS-5000? 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?

What makes the Omicron the better test set? I have used the Manta and did not like it. Does anyone have experience with the new Megger MPRT?

We recently purchased a Megger Delta 2000 Power Factor test set and experienced problems immediately. Every time we used the unit we had either erroneous readings or the unit reported an internal error. We had to use a Doble M4100. Megger supplied us with a loaner unit while ours was being...

Thanks for the information and replies. Does anyone have experience with Omicron? If so does it handle older electromechanical relays well?

The biggest reason we are moving from the 2200 series is size and weight. You have to setup 3 of them to test any new relay. 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...

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...
