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 measured earth fault element.
2. IN1>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 measured earth fault element.
3.
IN1>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 measured earth fault element.
4. IN1>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. IN1>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.
IN1>1 Reset Char
DT
DT/IDMT
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 (I
N1>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.)
