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.
