Parameter
Default setting
Setting Range
This setting determines the type of reset/release characteristics. IDMT applicable for IEEE curves only.
7.
IN1>1 RTMS
1
0.025 to 1.2 step 0.005
This setting determines the reset/release time for IEEE IDMT characteristic
8. IN1>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. IN1>1 2H Blocking Disabled Enabled/Disabled
This setting determines the enabling/disabling of blocking first stage measured earth fault element due to presence of inrush current.
If IN1>1 Blocking and 2nd Harmonic both settings
are enabled, then (IN1>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.)

This setting determines the tripping characteristic for the second stage measured earth fault element.
2. IN1>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 measured earth fault element.
3. IN1>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 of measured earth fault element.
4.
IN1>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. IN1>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. IN1>2 Reset Char DT DT/IDMT
This setting determines the type of reset/release characteristics. IDMT applicable for IEEE curves only.
7.
IN1>2 RTMS
1
0.025 to 1.2 step 0.005
This setting determines the reset/release time for IEEE IDMT characteristic
8. IN1>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. IN1>2 2H Blocking Disabled Enabled/Disabled
This setting determines the enabling/disabling of blocking second stage measured earth fault element due to presence of inrush current.
If IN1>2 Blocking and 2nd Harmonic both setting are enabled, then (IN1>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.)
