100ms rms Event Recording

The 100ms rms event capture gives you a different view of an event by

 

recording 100ms data for the amount of time you specify. Table 8–3lists all

 

the quantities captured. This type of event capture is useful for analyzing

 

what happened during a motor start or recloser operation because it shows

 

a long event without using a significant amount of memory. The circuit

 

monitor initiates the event capture automatically when an alarm condition

 

occurs, or an external device can also trigger the event capture. You select

 

the duration of the event recording (up to 300 seconds) and the number of

 

pre-event seconds (1–10) that the circuit monitor will capture.
