Technical Manual
ALARM is activated when two or more consecutive SMV frames are lost or late. A
single loss of frame is corrected with a zero-order hold scheme. In this case, the effect
on protection is considered negligible and the WARNING or ALARM outputs are not
activated. The output is held on for 10 seconds after the conditions return to normal.
The SMV Max Delay parameter defines how long the receiver waits for the SMV
frames before activating the ALARM output. This parameter can be accessed via
Configuration/System/Common. Waiting of the SMV frames also delays the local
measurements of the receiver to keep them correctly time aligned. The SMV Max
Delay values include sampling, processing and network delay.
The WARNING output in the receiver is activated if the synchronization accuracy of
the sender or the receiver is worse than 4 μs. The output is held on for 10 seconds after
the synchronization accuracy returns within limits.
The WARNING output is always internally active whenever the ALARM output is
active.
