GROUP 1 – NEG SEQUENCE O/C
I2>1 Time VTS 0.200 s 0 s 100.0 s 0.01 s
Sets the VTS time-delay. The VTS alarm will occur if VT fault occurs during more than the
VTS time-delay.
I2>1 TMS 1.000 0.025 1.200 0.005
Sets the Time Multiplier Setting (TMS), to adjust the operating time of the IEC IDMT
characteristics.
I2>1 Time Dial 1.000 0.01 100.0 0.01
Sets the time dial settings, to adjust the operating time of the IEEE/ US IDMT curves. The
Time Dial is a multiplier of the standard curve equation, to achieve the required tripping
time. The reference curve is based on Time Dial = 1.
Care: Certain manufacturer’s use a mid-range value of time dial = 5 or 7. So; it may be
necessary to divide by 5 or 7 to achieve parity.
I2>1 Reset Char DT DT, Inverse
Setting to determine the type of reset / release characteristics of IEEE / US curves.
I2>1 tReset 0 s 0 s 100.0 s 0.01 s
Setting that determines the reset / release time reset characteristics.

I2>2 Directional Non Directional Non-Directional, Directional FWD, Directional
REV
Sets the second phase overcurrent threshold (I2>2) characteristics. The conditions are
‘disabled’, definite time (DT) or inverse definite minimum time (IDMT).
Settings are the same as for the first stage overcurrent element.

I2>3 Status Disabled Disabled, Enabled
The third element is fixed as non-directional, for instantaneous or definite time delayed
tripping.
I2>3 Directional Non Directional Non-directional, Directional FWD, Directional REV
