Study Notes

Alarms

An alarm is triggered by a single source and a single measurement
When the voltage threshold is exceeded, the alarm goes active
When the voltage drops below the threshold, the alarm goes inactive
The alarm can be instantaneous, meaning that the start time (T1) and end time (T2) are identical

Incidents

An incident combines alarms, waveforms, and burst data from many sources into a single group
The Incident grouping time interval is different for different alarm types
PME uses the alarm types and alarm start times as criteria of grouping
If a new alarm occurs within a certain time interval, it is grouped into the same incident
The maximum duration for an incident is 24 hours

Alarm Status View User Interface

Alarm status table rows represent the alarms
Alarm status table columns represent the alarm information
The details button gives access to the details of a specific alarm

Alarm Definition Details

The alarm definition details display information about the alarm
Some of the information presented in the interface includes details, actions and the selector
The selector displays information through a number of different views
The actions section allows the user to add, edit, or delete the actions that will be taken in the event that the alarm is triggered

Alarm History View User Interface

The table rows in the Alarm History View represent the alarms
The details button gives access to the details of a specific alarm

Alarm Instance Details

The alarm instance details display information about the alarm instance
Some of the information presented in the interface includes details, actions and the selector

Incident History User Interface

The table rows in the Incident History View represent the incidents
The details button gives access to the details of a specific incident
The analysis button opens the timeline analysis window for the incident

Incident Details

Display selector allows the user to switch between different views of the incident
Incident Details information displays details about the incident
Actions section allows the user to take different actions related to the incident

Incident - Timeline Analysis

The timeline analysis window gives insight into the incident
The display includes burst data, load loss, captured waveform and the analysis item options
The user can zoom in and out or access the heatmap view
The options menu allows the user to adjust the display of the data

Waveform Viewer

The waveform timeline allows the user to view the historical, logged measurements
The inspect button allows the user to view the waveform viewer
The page selector allows the user to move between individual pages

Software Alarms Configuration Considerations

Configuring many Alarm Rules with short update intervals can affect overall system performance
The Alarm Rule name must be unique within the system
The Alarm Name must be unique for a given source
Alarm state is not evaluated if a device is disabled
Communication Loss Alarms are only applied to physical devices

Alarm Schedule

Schedules are applied in the time zone of each source
Alarms are deactivated when their schedule transitions to inactive
Real-time measurement alarms and communication status alarms are only evaluated when the schedule is active
Historical measurement alarms are only evaluated against data that was logged when the schedule was active

Key Points

The Alarms application is accessed through Views
Waveform data is based on logged, historical measurements that were recorded by a monitoring device
