Protection Elements Accuracy
The tripping delay relates to the time between alarm and trip.
The accuracy of the operating time relates to the time between fault entry and
the time when the protection element is picked-up.
Reference conditions for all Protection Elements: sine wave, at rated frequency, total harmonic distortion < 1%
Overcurrent Protection Elements:
50P[x] / 67P[x]
Accuracy
