DESCRIPTION
En VTSandCh Fail
Setting that defines second stage overcurrent operating status. Depending on 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.
I>2 Function 35 0B IEC S Inverse
IEC S Inverse
IEC V Inverse
IEC E Inverse
UK LT Inverse
IEEE M Inverse
IEEE V Inverse
IEEE E Inverse
US Inverse
US ST Inverse
Default Curve 1
Default Curve 2
Default Curve 3
Default Curve 4
Setting for the tripping characteristic for the second stage overcurrent element.
I>2 Directional 35 0C Non-Directional
Directional Fwd
Directional Rev
[Indexed String]
This setting determines the direction of measurement for second stage element.
I>2 Current Set 35 0D 1
From 0.08*I1 to 4.0*I1 in steps of 0.01*I1
[Courier Number (current)]
Pick-up setting for second stage overcurrent element.
I>2 Time Delay 35 0E 1
From 0 to 100 in steps of 0.01
[Courier Number (time-seconds)]
Setting for the time-delay for the definite time setting if selected for second stage element. The setting is visible only when DT function is
selected.
I>2 TMS 35 0F 1
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.
I>2 Time Dial 35 10 1
From 0.01 to 100 in steps of 0.01
[Courier Number (decimal)]
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>2 Reset Char 35 11 DT
Inverse
Setting to determine the type of reset/release characteristic of the IEEE/US curves.
I>2 tRESET 35 12 0
From 0 to 100 in steps of 0.01
[Courier Number (time-seconds)]
Setting that determines the reset/release time for definite time reset characteristic
I>3 Status 35 13 Disabled
Enabled
Enabled VTS
Enabled Ch Fail
En VTSorCh Fail
En VTSandCh Fail
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
