Commonly used terms in the Electrical industry.

Potier reactance
the leakage reactance obtained in a particular manner from a test on a synchronous machine at full load with a power factor of zero lagging. The test requires little power but supplies the excitation for short circuit and for normal rated voltage both at full-load current at zero power factor. The Potier reactance is determined
by a graphical manner from the open circuit characteristic and the short circuit point for full-load current.
