4.3. Monitoring
Monitoring is the first Menu option in the Web-HMI below the Dashboard. Monitoring
menu offers options where user can monitor the device status, events and records.
4.3.1. Self-Supervision
The EAGLE has continuous self-monitoring capability. If any internal errors or
abnormalities are found, they are indicated in the Self Supervision page in the form of an
error code.
The displayed error code can be shared with an ABB technical support person for the
correct diagnosis of the error & subsequent actions.
4.3.2. Events & Fault Records
Event Logs are one of the most important pieces of evidence for post fault system event
investigation. They can provide the reasons for premature equipment failures and give
necessary information to perform post-fault event analysis. Proper use and interpretation
of event records can lead to corrective action for a given system problem resulting in
improved performance and reliability of the distribution system.
The event logging is triggered by the activation and deactivation of protection start, trip,
Binary Input (BI)/Binary Output (BO) status changes, system faults, recloser status changes,
setting changes etc. The logged events are stored in a non-volatile memory and made
available for download as ASCII CSV text file.
Two type of event logs are maintained in the recloser:
1. Internal Events – Events related to device status
2. External Events – Events generated by user activity or protection function
operation
The events can be filtered or searched to see specific entries or only internal (i.e. Device)
or external events. If fault record option is selected, only the protection related events are
filtered. Sorting can also be done by date, event type and description.
The pickup and dropout or assertion and desertion of events are represented by "↑" and
"↓" respectively after the event description text.
Total 100 internal events and 1000 external events will be stored. If the number of events
logged reaches maximum limit, the oldest event will be replaced and overwritten with the
latest event.
All events can be download on to the handheld device. All external events can be cleared
if logged in as an "Admin". The view of Events page as an "Admin" is presented below.
The detailed list of internal and external events is shown in Appendix 2: List of Events
