MENU TEXT
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
This setting determines the direction of measurement for the third stage overcurrent element.
I>3 Current Set
Pick-up setting for third stage overcurrent element.
I>3 Time Delay
Setting for the operating time-delay for third stage overcurrent element.
I>4 Status
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
I>4 Status
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
This setting determines the direction of measurement for the fourth stage overcurrent element.
I>4 Current Set
Pick-up setting for fourth stage overcurrent element.
I>4 Time Delay
Setting for the operating time-delay for fourth stage overcurrent element.
I> Char 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
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.
