Loss of Excitation - Generator DC exciter current supervision, over-, undercurrent and diode failure detection. 0 - 300 Hz, Exciter overcurrent: I> = 0 - 15 A (min 0,2 A) tI> = 0 - 5 s / 0 - 50 s; Exciter undercurrent: I< = 0 - 5 A (min 0,2 A) tI< = 0 - 5 s / 0 - 50 s; Diode Failure detection: IR> 0 - 125 % (min 10 %)
FEATURES & FUNCTIONALITY
Loss of Excitation - Generator DC exciter current supervision, over-, undercurrent and diode failure detection. 0 - 300 Hz
The relay XE2 of the easy PROFESSIONAL LINE is used for supervision of the exciter current. By the exciter current element the direct current of the excitation machine in brushless machines is supervised. The protection function includes detection of overcurrent and undercurrent as well as supervision of the ripple component of the exciter current and so faults of the rotating diodes would be revealed.
The XE2 is compliant with IEC 60255-1.
