Appendix B -Settings and Signals
MENU TEXT
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
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 relay 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.
GROUP 1: NEG SEQ O/C
This column contains settings for Negative Sequence overcurrent
I2>1 Status
Setting to enable or disable the first stage negative sequence element.
I2>1 Function
Setting for the tripping characteristic for the first stage negative sequence overcurrent element.
I2>1 Direction
This setting determines the direction of measurement for this element.
I2>1 Current Set
Pick-up setting for the first stage negative sequence overcurrent element.
I2>1 Time Delay
Setting for the operating time-delay for the first stage negative sequence overcurrent element.
I2>1 TMS
Setting for the time multiplier setting to adjust the operating time of the IEC IDMT characteristic.
