DESCRIPTION
To invert polarity (180 °) of the SEF CT
M CT Polarity 0A 14 Standard
Inverted
To invert polarity (180 °) of the Mutual CT
VT Connected 0A 18 Yes
Yes
To indicate if voltage transformers are connected to the IED. This MUST be set properly to ensure Pole Dead logic works correctly. If set to
‘No’, it will set VTS Slow Block and VTS Fast Block DDB's, but will not raise any alarms. It will also override the VTS enabled setting should the
user set it. If set to ‘Yes’ this setting will have no effect.
CS VT Ph Shift 0A 21 0
From -180 to 180 in steps of 5
[Courier Number (angle)]
Phase angle difference between selected phase ("C/S Input" 0A 0F) of Line VT input and applied "CB CS" VT input voltage under healthy
system conditions
CS VT Mag 0A 22 1
From 0.2 to 3 in steps of 0.01
[Courier Number]
Ratio of voltage magnitudes of selected phase ("C/S Input" 0A 0F) of Line VT input and applied "CB CS" VT input voltage under healthy system
conditions
This column contains settings for Record Controls
Alarm Event 0B 04 Enabled
Enabled
Disabling this setting means that no event is generated for alarms
Relay O/P Event 0B 05 Enabled
Enabled
Disabling this setting means that no event will be generated for any change in logic output state.
Opto Input Event 0B 06 Enabled
Enabled
Disabling this setting means that no event will be generated for any change in logic input state.
General Event 0B 07 Enabled
Enabled
Disabling this setting means that no General Events are generated
Fault Rec Event 0B 08 Enabled
Enabled
Disabling this setting means that no event will be generated for any fault that produces a fault record
Maint Rec Event 0B 09 Enabled
Enabled
Disabling this setting means that no event will be generated for any occurrence that produces a maintenance record.
Protection Event 0B 0A Enabled
Enabled
Disabling this setting means that any operation of protection elements will not be logged as an event
Flt Rec Extended 0B 2F Disabled
Enabled
[Indexed String]
When this setting is disabled, the fault record contains a snap shot of the local, remote, differential and bias currents taken 1 cycle after the
trip.
With this setting enabled an additional snap shot of local, remote, differential and bias currents taken at the time the differential trips is
included in the fault record.
DDB 31 - 0 0B 40 0xFFFFFFFF
High order word of long stored in 1st register
Low order word of long stored in 2nd register
Chooses whether any individual DDB's should be deselected as a stored event, by setting the relevant bit to 0 (zero). Typically used for
