Megger DLRO10HD vs 1000KVA XFMR

Has anyone tried to find winding resistance with a Megger DLRO10HD on a 1000KVA XFMR with any success. We tried today and it was almost as if the ductor cut off because it just didn’t have the capacity, but an AEMC will do it. Any info greatly appreciated.

Did you adjust the scale down? Use the coil setting. It works better when you use leads with clamps, this way you can’t slip.

I have noticed that the two DLRO10HD’s i have had both have issues with the batteries and the 10 amp setting goes out and eventually the rest of the settings go out and you have to replace the battery to fix it…then the cycle repeats. I have done windings a couple times and once this issue begins with mine it just wont read windings well.
