FC610 records events triggered by voltage dip, voltage swell, Interruption, over current through
event curves. Current and voltages curves including I1, I2, I3, U1, U2, U3, U12, U23, and U31 of
each triggered event are recorded in FC610. Only the last 10 records are saved in FC610 for each
event type.
Each event curve is recorded from event pre-trigger point until event recovery stage through
120 samples or 240 samples. The sampling frequency is every half cycle. For example, in a 50Hz
system, the sampling frequency is every 10ms.
When an event, from detection to recovery, completes within 120 samples time, the event will
still be recorded with 120 samples (Figure 23). If an event is longer than 120 samples time, the
event will be recorded through 240 samples instead, with 120 samples recorded during event
detected period and the other 120 samples during event recovery period. (Figure 24)
The pre-trigger point of an event is configurable from 30% -70% of the sampling range before
the event is detected. For example, if 30% is configured as pre-trigger level in a 50Hz system,
36 samples are recorded before the event is triggered while 84 samples are recorded after the
event is detected. Similarly, another 36 samples are recorded before the event is recovered and
84 samples after recovery
