Appendix B -Settings and Signals
MENU TEXT
Length of LOL window - the time window in which Zone 2 accelerated tripping can occur following LOL undercurrent detector operation.
GROUP 1:
OVERCURRENT
This column contains settings for Overcurrent
I>1 Status
Setting that defines first stage overcurrent operating status. Depending of this setting, I>1 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>1 Function
Setting for the tripping characteristic for the first stage overcurrent element.
I>1 Direction
This setting determines the direction of measurement for first stage element.
I>1 Current Set
Pick-up setting for first stage overcurrent element.
I>1 Time Delay
Setting for the time-delay for the definite time setting if selected for first stage element. The setting is visible only when DT function is
selected.
I>1 TMS
Setting for the time multiplier setting to adjust the operating time of the IEC IDMT characteristic.
I>1 Time Dial
Setting for the time multiplier setting to adjust the operating time of the IEEE/US IDMT curves. The Time Dial (TD) is a multiplier on the
standard curve equation, in order to achieve the required tripping time. The reference curve is based on TD = 1.
Care: Certain manufacturer's use a mid-range value of TD = 5 or 7, so it may be necessary to divide by 5 or 7 to achieve parity.
I>1 Reset Char
Setting to determine the type of reset/release characteristic of the IEEE/US curves.
I>1 tRESET
Setting that determines the reset/release time for definite time reset characteristic
I>2 Status
Setting that defines second stage overcurrent operating status. Depending of this setting, I>2 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.
