Figure 7.7 is a sample event history from a terminal.
Fault location data can be indeterminate (for example, when you trigger an event
and there is no fault on the power system). If this is the case, the relay displays
$$$$.$$ for the Location entry in the event history. You will also see the $$$$.$$
display if the fault location enable setting EFLOC is N.
The event types in the event history are the same as the event types in the event
summary (see Table 7.10 for event types).
