First, thanks to Jason for the heads up! Taking credit for premium
efficiency transformers is a pretty novel idea in my circles.

I'm re-directing this response/discussion to eQuest-users as I'm
applying this in eQuest and have found a snag along the way...

After coming up with and creating a custom TRANS-LOSS-FPLR curve using
manufacturer data, I hop over to create a new meter to assign this to.
The default transformer size field starts off blank, as transformer
losses are not normally modeled. After entering the transformer size
(225kVA) on the first screen, I immediately encounter the following
dialog:

[text includes: "Range Checking Violation: Value must be > 1"]

Hmm. This seems odd... the text files for TRANSFORMER-LOSS and
TRANS-LOSS-FPLR both indicate this value should be a fraction of the
Transformer size representing the maximum loss (therefore < 1). In my
example, the 225kVA transformer has a maximum loss (at full load) of
3,898VA, so I was expecting TRANSFOMER-LOSS should be 3898/225000 =
0.01732. Regardless, I haven't entered anything in that field yet... so
clicking Cancel to proceed, I return to the following:

Hmm.

The error appears to result from the "Loss:" field being unpopulated. I
cannot however input the Loss ratio (clouded "n/a") for the custom curve
to be applied against! The field ignores anything I type when
highlighted...

Okay so saving and exiting, I navigate the .inp to add TRANSFORMER-LOSS
there:

"Step Down Meter" = ELEC-METER

TYPE = BUILDING

TRANSFORMER-SIZE = 225

TRANSFORMER-LOSS = .01732

TRANS-LOSS-FPLR = "Custom Xfrmr fPLR"

..

Starting eQuest back up, the following error is generated in BDL -
(eQuest proceeds to open and overwrite .01732 with a zero):

*13249* "Step Down Meter" = ELEC-METER

*13250* TYPE = BUILDING

*13251* TRANSFORMER-SIZE = 225

*13252* TRANSFORMER-LOSS = .01732

*ERROR**************************** ======
****************************************************

*ERROR*****VALUE NOT BETWEEN 1.0000 AND 1.5000

*13253* TRANS-LOSS-FPLR = "Custom Xfrmr fPLR"

Here's where I throw up my hands! What interpretation of
TRANSFORMER-LOSS results in a value that would always fall between 1.0
and 1.5?

On a related note: I've read through all the help files regarding
electrical meters (I think)... Once this is meter up and running, can
anyone suggest any method for applying a specific subset of electric
loads (say, only plug loads) to this new meter with the transformer
losses defined?
