Parameter
Default setting
Setting Range
3. I>lift 2H 10*In 4*In to 32*In step 0.01*In
The 2nd harmonic blocking is applied only when the fundamental current is above 2nd Harm Thresh and below I> lift setting. The reset
levels are 95% of these thresholds.
2.12.2 OVERCURRENT Settings
2.12.2.1 I>1 Function
Sr. No Parameter Default setting Setting Range
1. I>1 Function IEC S Inverse
Disabled/DT/IEC S Inverse/S Inverse 1.3Sec
/
IEC V Inverse/IEC E Inverse/UK LT Inverse/
IEEE M Inverse/IEEE V Inverse/IEEE E
Inverse/US Inverse/US ST Inverse
This setting determines the tripping characteristic for the first stage overcurrent element.
2. I>1 Current Set 1*In
If DT 0.05 to 35*In step 0.01*In
If IDMT then 0.05 to 4*In step 0.01*In
This setting determines the pick-up setting for first stage overcurrent element.
3. I>1 Time Delay 1 S 0 to 100s step 0.01s
This setting determines the time-delay for the definite time setting if selected for first stage overcurrent element.
4.
I>1 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. I>1 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. I>1 Reset Char DT DT/IDMT
This setting determines the type of reset/release characteristics. IDMT applicable for IEEE curves only.
7.
I>1 RTMS
1
0.025 to 1.2 step 0.005
This setting determines the reset/release time for IEEE IDMT characteristic
8. I>1 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. I>1 2H Blocking Disabled Enabled/Disabled
This setting determines the enabling/disabling of blocking first stage overcurrent element due to presence of inrush current.
If I>1 Blocking and 2nd Harmonic both settings are enabled, then (I>1) 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.)
2.12.2.2 I>2 Function

This setting determines the tripping characteristic for the second stage overcurrent element.
2. I>2 Current Set 1*In
If DT 0.05 to 35*In step 0.01*In
If IDMT then 0.05 to 4*In step 0.01*In
This setting determines the pick-up setting for second stage overcurrent element.
3.
I>2 Time Delay
1 S
0 to 100s step 0.01s
This setting determines the time-delay for the definite time setting if selected for second stage overcurrent element.
4. I>2 TMS 1 0.025 to 1.200 step 0.005
This time multiplier setting is used to adjust the operating time of the IEC/UK IDMT characteristic.
