Hi Brian,

 

I’m not sure which version of eQuest you’re using.  Version 3.64 defaults to
0.02.  If you right click on the transformer loss box you can change this to
whatever you want.

The transformer loss in eQUEST should be the fraction of output power lost
at full load.  It should be in the order of 1 to 3% so an input of 0.02 for
example.  However the range checking in eQUEST is looking for a value
greater than 1 (in the range of 1 – 1.5).  A value of 1 does in fact double
your electrical usage (with ½ going to Pumps and Aux for the transformer
loss) so the range checking is in error.

 



 

Is there a way to access and change the error checking values?

 

Thank you.

 

Brian
