DESCRIPTION
Setting that defines fourth stage overcurrent operating status. Depending of 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 Direction 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 relay 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.

From 0.025 to 1.2 in steps of 0.005
[Courier Number (decimal)]
Setting for the time multiplier setting to adjust the operating time of the IEC IDMT characteristic.
I2>1 Time Dial 36 19 1
From 0.01 to 100 in steps of 0.01
[Courier Number (decimal)]
