E Inverse/US Inverse/US ST Inverse
This setting determines the tripping characteristic for the third stage measured earth fault element.
2. IN1>3 Current Set
0.2*In If DT 0.002 to 2*In step 0.001*In
If IDMT then 0.002 to 0.2*In step 0.001*In
This setting determines the pick-up setting for third stage measured earth fault element.
3. IN1>3 Time Delay 1 S 0 to 200s step 0.01s
This setting determines the time-delay for the definite time setting if selected for third stage of measured earth fault element.
4.
IN1>3 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. IN1>3 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. IN1>3 Reset Char DT DT/IDMT
This setting determines the type of reset/release characteristics. IDMT applicable for IEEE curves only.
7.
IN1>3 RTMS
1
0.025 to 1.2 step 0.005
This setting determines the reset/release time for IEEE IDMT characteristic
8. IN1>3 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. IN1>3 2H Blocking Disabled Enabled/Disabled
This setting determines the enabling/disabling of blocking third stage measured earth fault element due to presence of inrush current.
If IN1>3 Blocking and 2nd Harmonic both settings are enabled, then (IN1>3
) 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 first stage derived earth fault element.
2. IN2>1 Current Set 1*In
If DT 0.10 to 35*In step 0.01*In
If IDMT then 0.10 to 4*In step 0.01*In
This setting determines the pick-up setting for first stage derived earth fault element.
3. IN2>1 Time Delay 1 S 0 to 200s step 0.01s
This setting determines the time-delay for the definite time setting if selected for first stage of derived earth fault element.
4. IN2>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.
IN2>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. IN2>1 Reset Char DT DT/IDMT
