connection between the two lines of the diameter in the breaker-and-a-half switchyard
layout.
For a breaker-and-a-half arrangement, the modules BH_LINE_A, BH_CONN and
BH_LINE_B must be used.
Configuration setting
For application without 989 and 989G, just set the appropriate inputs to open state and
disregard the outputs. In the functional block diagram, 0 and 1 are designated
0=FALSE and 1=TRUE:
• 989_OP = 1
• 989_CL = 0
• 989G_OP = 1
• 989G_CL = 0
If, in this case, line voltage supervision is added, then rather than setting 989 to open
state, specify the state of the voltage supervision:
• 989_OP = VOLT_OFF
• 989_CL = VOLT_ON
If there is no voltage supervision, then set the corresponding inputs as follows:
• VOLT_OFF = 1
• VOLT_ON = 0
