Independent of the event recorder, the relay captures the system information at the time of
the last trip event. This information includes a time and date stamp, trip cause, phase
current, ground current, sensitive ground current, neutral current, voltages, system
frequency, and the analog input. If more than one protection element trips for a fault (for
example, both the Phase and Neutral Instantaneous Overcurrent 1 elements) then only the
first trip event detected by the relay will have Last Trip Data captured. This information
cannot be cleared; data for a new trip overwrites the previous trip data.
The AN, BN, and CN voltage values are seen only if the
