Parameter
Default setting
Setting Range
This setting determines the tripping characteristic for the second stage Negative sequence overcurrent element.
2. I2>2 Current Set 1*In
If DT 0.1 to 35*In step 0.01*In
If IDMT then 0.1 to 4*In step 0.01*In
This setting determines the pick-up setting for second stage Negative sequence overcurrent element.
3.
I2>2 Time Delay
1 S
0 to 200s step 0.01s
This setting determines the time-delay for the definite time setting if selected for second stage Negative sequence overcurrent element.
4. I2>2 TMS 1 0.025 to 1.2 step 0.005
This time multiplier setting is used to adjust the operating time of the IEC/UK IDMT characteristic.
5. I2>2 Time Dial 1 0.01 to 100 step 0.01
This time multiplier setting is used to adjust the operating time of the IEEE/US IDMT curves.
6.
I2>2 Reset Char
DT
DT/IDMT
This setting determines the type of reset/release characteristics. IDMT applicable for IEEE curves only.
7. I2>2 RTMS 1 0.025 to 1.2 step 0.005
This setting determines the reset/release time for IEEE IDMT characteristic
8. I2>2 tRESET 0.01 S 0 to 100s step 0.01s
This setting determines the reset/release time for Definite Time (DT) and all IDMT curve
9.
I2>2 2H Blocking
Disabled
Enabled/Disabled
This setting determines the enabling/disabling of blocking second stage Negative sequence overcurrent element due to presence of
inrush current.
If I2>2 Blocking and 2nd Harmonic both settings are enabled, then (I2>2) trip command will be blocked in case 2nd harmonics content in
any phase is above the 2ndHarm Thresh. and fundamental current is below I> lift 2H setting. (Set in SYSTEM CONFIG Menu.)

This setting determines the tripping characteristic for the third stage Negative sequence overcurrent element.
2. I2>3 Current Set 1*In
If DT 1 to 35*In step 0.01*In
If IDMT then 0.1 to 4*In step 0.01*In
This setting determines the pick-up setting for second third Negative sequence overcurrent element.
3. I2>3 Time Delay 1 S 0 to 200s step 0.01s
