15 CURR RIPP
Armature current ripple
One or several thyristors carry no current.
Check: - Current feedback with oscilloscope
(6 pulses within one cycle visible?);
- Branch fuses, thyristor gate con-
nection and gate-cathode resis-
tance;

Alarm: Armature Current Deviation
If the current reference ARM_CUR_REF
[P 3.12]
deviates from the current feedback
for more than 5 sec by more than 20 %,
referenced to the rated current, this signal
will be shown.
Check: - Ratio between mains supply
voltage and EMF
