Transient alarms

Transient alarms are triggered by voltage transient activity (for example, ITI CBEMA Type 1 disturbances).

You must configure nominal voltage for these alarms to function.

The Threshold setup register in the Transient module defines what voltage disturbance magnitude should be considered as transient activity. Threshold is interpreted as a percentage of the nominal system voltage, plus 100. For example, if you want transients recorded when voltage deviates from nominal by 20%, enter 120 into the Threshold setup register.
