GROUP 1 – SYSTEM CHECK
C/S Check Scheme for Man
CB
Check synchronism scheme for Manual CB Closure. At least, one condition must be
selected to activate the synchronism check logic. The Dead Bus / Dead Line can only be
created using PSL.
The check synchronism condition is only taken into account if a SOTF condition has been
enabled. Otherwise, a dedicated PSL can be created using DDB (live line or live bus/dead
line) – live/live cannot be managed – in that case.
V< Dead Line
V> Live Line
V< Dead Bus
V> Live Bus
The Live Line and Dead Line settings define the thresholds which dictate whether or not the
line or bus is determined as being live or dead by the relay logic.
Diff Voltage
Differential voltage between Line VT and Busbar VT measurements.
Diff Frequency
Differential frequency between Line VT and Busbar VT measurements.
Diff Phase
Differential voltage between Line VT and Busbar VT measurements.
Bus-Line Delay
Bus Line time delay: The Check synchronism is not verified when 'V> Live Bus', 'V> Live
Line', 'Diff Voltage', 'Diff Frequency' or 'Diff Phase' threshold is exceeded for longer than
'Bus-Line delay' time-delay.
