[RE-wrenches] Large transformer losses

> > > Hi Jay, A 75kVA low voltage transformer will have roughly 0.3% iron core losses and have an efficiency loss of roughly 2%. It depends on when the transformer was made and what efficiency standard it was adhered to. the manufacturer should be able to provide you with the testing results if

Should be easy enough to look up on the manufacturer’s website. William Miller Miller Solar.com 805-438-5600 www.millersolar.com On Fri, Apr 26, 2024 at 3:54 PM Jay via RE-wrenches < re-wrenches@lists.re-wrenches.org> wrote: > Hi all. > > Anyone know what the tare loss and efficiency is of a 75

Do you know the transformer impedance? On Fri, Apr 26, 2024, 5:54 PM Jay via RE-wrenches < re-wrenches@lists.re-wrenches.org> wrote: > Hi all. > > Anyone know what the tare loss and efficiency is of a 75 kw transformer? > And it would be run mostly at 1-10kw max. > > This one specifically. > hamm

Re: [RE-wrenches] Large transformer losses

Hi Jay I have gotten this type of information directly from Hammond, I would think from transformer to House line loss should be considered. From my Experiance, people go to 400 amp services mostly for circuit count. I have measured a few transformers in past but I don't know where data is now.

Hi all. Anyone know what the tare loss and efficiency is of a 75 kw transformer? And it would be run mostly at 1-10kw max. This one specifically. hammond SG3L0075PE I’m just curious about it. The situation is 240vac grid at the street, 600’ to the house 400 amps. Why 400 amps on a house w
