P50 Agile P153 7 Protection Parameter Settings
P153/EN M/B 7-13
Sr. No Parameter Default setting Setting Range
4. IN1>1 TMS 1.000 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 1.00 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 1.000 0.025 to 1.2 step 0.005
This setting determines the reset/release time for IEEE IDMT characteristic
8.
IN1>1 tRESET 1.00 S 0s 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 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.)
2.12.3.2 IN1>2 Function
Sr. No Parameter Default setting Setting Range
1. IN1>2 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 second stage measured earth fault element.
2. IN1>2 Current Set 1.00*In
If DT 0.05 to 35.00*In step 0.01*In
If IDMT then 0.05 to 4.00*In step 0.01*In
This setting determines the pick-up setting for second stage measured earth fault element.
3.
IN1>2 Time Delay 1.00 S 0s 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 1.000 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.

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 settings 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.)
