DESCRIPTION
En VTSorCh Fail
En VTSandCh Fail
[Indexed String]
Setting that defines third stage overcurrent operating status. Depending on this setting, I>3 will be enabled permanently or in case of
Voltage Transformer Supervision (fuse fail) operation, or in case of communication channel fail, or a combination (and /or) of both.
I>3 Directional 35 14 Directional Fwd
Non-Directional
Directional Fwd
Directional Rev
[Indexed String]
This setting determines the direction of measurement for the third stage overcurrent element.
I>3 Current Set 35 15 10
From 0.08*I1 to 32*I1 in steps of 0.01*I1
[Courier Number (current)]
Pick-up setting for third stage overcurrent element.
I>3 Time Delay 35 16 0
From 0 to 100 in steps of 0.01
[Courier Number (time-seconds)]
Setting for the operating time-delay for third stage overcurrent element.

Setting that defines fourth stage overcurrent operating status. Depending on this setting, I>4 will be enabled permanently or in case of
Voltage Transformer Supervision (fuse fail) operation

En VTSorCh Fail
En VTSandCh Fail
[Indexed String]
Setting that defines fourth stage overcurrent operating status. Depending on this setting, I>4 will be enabled permanently or in case of
Voltage Transformer Supervision (fuse fail) operation, or in case of communication channel fail, or a combination (and /or) of both.
I>4 Directional 35 19 Non-Directional
Non-Directional
Directional Fwd
Directional Rev
[Indexed String]
This setting determines the direction of measurement for the fourth stage overcurrent element.
I>4 Current Set 35 1A 10
From 0.08*I1 to 32*I1 in steps of 0.01*I1
[Courier Number (current)]
Pick-up setting for fourth stage overcurrent element.
I>4 Time Delay 35 1B 0
From 0 to 100 in steps of 0.01
[Courier Number (time-seconds)]
Setting for the operating time-delay for fourth stage overcurrent element.
I> Char Angle 35 1C 30
From -95 to 95 in steps of 1
[Courier Number (angle)]
Setting for the IED characteristic angle used for the directional decision. The setting is visible only when ‘Directional Fwd’ or ‘Directional Rev’
is set.
I> Blocking 35 1D 0xF
VTS Blocks I>1
VTS Blocks I>2
VTS Blocks I>3
VTS Blocks I>4
[Binary Flag (16 bits)]
Logic Settings that determine whether blocking signals from VT supervision affect certain overcurrent stages.
VTS Block – only affects directional overcurrent protection. With the relevant bit set to 1, operation of the Voltage Transformer Supervision
(VTS), will block the stage. When set to 0, the stage will revert to Non-directional upon operation of the VTS.
If I> Status is set ‘Enabled VTS’, no blocking should be selected in order to provide fault clearance by overcurrent protection during the VTS
condition.
