P50 Agile P253
Sr. No
This setting determines the type of reset/release characteristics. IDMT applicable for IEEE curves only.
7.
This setting determines the reset/release time for IEEE IDMT characteristic
8.
This setting determines the reset/release time for Definite Time (DT) and all IDMT curve
9.
This setting determines the enabling/disabling of blocking first stage derived earth fault element due to presence of inrush current.
If IN2>1 Blocking and 2nd Harmonic both settings are enabled, then (IN2>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.)
2.12.4.2
IN2>2 Function
Sr. No
1.
This setting determines the tripping characteristic for the second stage derived earth fault element.
2.
This setting determines the pick-up setting for second stage derived earth fault element.
3.
This setting determines the time-delay for the definite time setting if selected for second stage of derived earth fault element.
4.
This time multiplier setting is used to adjust the operating time of the IEC / UK IDMT characteristic.
5.
This time multiplier setting is used to adjust the operating time of the IEEE / US IDMT curves.
6.
This setting determines the type of reset/release characteristics. IDMT applicable for IEEE curves only.
7.
This setting determines the reset/release time for IEEE IDMT characteristic
8.
This setting determines the reset/release time for Definite Time (DT) and all IDMT curve
9.
This setting determines the enabling/disabling of blocking second stage derived earth fault element due to presence of inrush current.
If IN2>2 Blocking and 2nd Harmonic both settings are enabled, then (IN2>2) trip command will be blocked in case 2nd harmonics content

2.12.4.3
IN2>3 Function
Sr. No
1.
This setting determines the tripping characteristic for the third stage derived earth fault element.
2.
This setting determines the pick-up setting for third stage derived earth fault element.
