DESCRIPTION
bus voltages (refer to setting CS2 Slip Freq)
CB1 CS2 SlipCtrl 48 97 Enabled
Enabled
Setting to enable or disable blocking of synchronism check stage 2 for reclosing CB1 by excessive frequency difference (slip) between line
and bus voltages (refer to setting CB1 CS2 SlipFreq)
CS2 Slip Freq 48 98 0.05
From 0.005 to 2 in steps of 0.005
[Courier Number (frequency)]
If CS2 Slip Ctrl is enabled, synchronism check stage 2 is blocked for reclosing CB if measured frequency difference between line and bus
voltages is greater than this setting.
CB1 CS2 SlipFreq 48 98 0.05
From 0.005 to 2 in steps of 0.005
[Courier Number (frequency)]
If CB1 CS2 SlipCtrl is enabled, synchronism check stage 2 is blocked for reclosing CB1 if measured frequency difference between line and bus
voltages is greater than this setting.
CS2 Adaptive 48 99 Disabled
Enabled
Setting to enable or disable Adaptive CB closing with System Check Synchronism stage 2 closing for CB: logic uses set CB CI Time to issue CB
close command at such a time that the predicted phase angle difference when CB main contacts touch is as close as possible to 0 degrees.
If Adaptive closing is disabled, the logic issues CB close command as soon as phase angle comes within set limit at CB CS2 Angle .
CB1 CS2 Adaptive 48 99 Disabled
Enabled
Setting to enable or disable Adaptive CB closing with System Check Synchronism stage 2 closing for CB1: logic uses set CB1 CI Time to issue
CB1 close command at such a time that the predicted phase angle difference when CB1 main contacts touch is as close as possible to 0
degrees. If Adaptive closing is disabled, the logic issues CB1 close command as soon as phase angle comes within set limit at CB1 CS2 Angle
CB Cl Time 48 9A 0.05
From 0.01 to 0.5 in steps of 0.001
[Courier Number (time-seconds)]
This sets CB closing time, from receipt of CB close command until main contacts touch.
CB1 Cl Time 48 9A 0.05
From 0.01 to 0.5 in steps of 0.001
[Courier Number (time-seconds)]
This sets CB1 closing time, from receipt of CB1 close command until main contacts touch.
Sys Checks CB2 48 9B Disabled
Enabled
Setting to enable or disable both stages of system checks for reclosing CB2.
If Sys Checks CB2 is set to Disabled, all other menu settings associated with synchronism checks for CB2 become invisible, and a DDB (1484)
signal SChksInactiveCB2 is set.
CBM SC required 48 B2 Disabled
Enabled
This setting determines whether a system check (e.g. live bus / dead line etc) is required for any manual (operator-controlled) closure of CB. If
Enabled, system check is required for closure. If Disabled, system check is not required.
CB1M SC required 48 B2 Disabled
Enabled
This setting determines whether a system check (e.g. live bus / dead line etc) is required for any manual (operator-controlled) closure of CB1.
If Enabled, system check is required for closure. If Disabled, system check is not required.
CBM SC CS1 48 B3 Disabled
Enabled
This setting enables CB to close by manual control when the system satisfies all the System Check Synchronism Stage 1 conditions as listed
under the setting CS1 Status in the SYSTEM CHECKS column.
CB1M SC CS1 48 B3 Disabled
Enabled
This setting enables CB1 to close by manual control when the system satisfies all the System Check Synchronism Stage 1 conditions as listed
under the setting CB1 CS1 Status in the SYSTEM CHECKS column.
CBM SC CS2 48 B4 Disabled
