Outage
Class Description
Document describing details of an active or planned outage in a part of the electrical network. A non-planned outage may be created upon:
- a breaker trip,
- a fault indicator status change,
- a meter event indicating customer outage,
- a reception of one or more customer trouble calls, or
- an operator command, reflecting information obtained from the field crew. Outage restoration may be performed using a switching plan which complements the outage information with detailed switching activities, including the relationship to the crew and work. A planned outage may be created upon:
- a request for service, maintenance or construction work in the field, or
- an operator-defined outage for what-if/contingency network analysis.
