Alarm

There are 6 tabs in the Alarm page:



Alarm Settings

, go to page 29.



System Supervision

, go to page 31.



Partial Discharge

, go to page 33.



Bushing Insulation

, go to page 35.



Alarm Statuses

, go to page 37.

Note

: If the Alarms are set to “manual

acknowledgement” in the

Alarm Settings

tab, then alarms have to be

manually acknowledged and reset in this tab.



Relay Control

, go to page 46

Please note that the default alarm values for PD and bushing monitoring are

conservative, and therefore may be tight for some transformers. These alarm values
should be reviewed when the transformer is energised and again 1 month after
Intellix™ BMT 330 has been operational.
