MV transformer: no-load (iron) loss

No-load loss of the medium-voltage transformer, drawn day and night

Unit %

What it is

The no-load loss of the medium-voltage transformer, as a fraction of the reference power. It is drawn at every timestep unless the transformer is disconnected at night (Losses tab, Night disconnect).

Typical values and how to get it

The transformer's no-load loss in kilowatts divided by the reference power; about 0.1 %. If not given: 0: no transformer iron loss.
