Figure 2-9 Load Restoration - Blocking and Monitoring
After the monitoring time of the restoration cycle has elapsed, the success of the load restoration will be eval-
uated.
Success basically depends on the following criteria:
• The load restoration is not blocked, e.g. by another protective function, binary input, undervoltage, monitor-
ing
• The monitoring time of restoration cycles of every started load restoration elements has elapsed
• The maximum number of configured cycles was not exceeded
• All started load restoration elements are connected
