Line 6:

The curve is obtained by rotating the generator at the rated [[RPM]] with the output terminals disconnected and the output voltage typically going to at least 120% of the rated for the device. The hydraulic units sometimes have to be tested at lower RPM with the resulting voltage scaled up to accommodate the differences in frequency. Since the test goes above the rated voltage, the [[step-up transformer]] is typically also disconnected to avoid damaging it.{{sfn | Boldea | 2015 | p=412}}

The open circuit saturation curve could be used together with the [[zero power factor curve]] in Potier Triangle Method.<ref name="EEEguide">{{cite web | url=https://www.eeeguide.com/armature-reaction-in-synchronous-motor/ | title=Armature Reaction in Synchronous Motor | publisher=EEEguide – Online Electrical and Electronics Learning Site | access-date=2024-12-15 }}</ref>.
