7 Protection Parameter Settings
This setting determines the new time multiplier setting for the first stage derived earth fault element to adjust the operating time of the
IEEE / US IDMT characteristic during the tclp time.
38. IN2>2 Status Enabled Blocked / Enabled
The IN2>2 status cells have two setting options, "Enabled" and "Blocked". Selecting "Enabled" for a particular stage means that the
current and time settings programmed in the following cells will be adopted during the "tclp" time. Selecting of "Blocked" s
relevant protection stage during the "tclp" time. It also removes the following current and time settings for that stage from the menu.
0.10 to 4.00*In step 0.01*In
This setting determines the new pick-up setting for second stage earth fault element during the tclp time delay.
39. IN2>2 Current Set 0.20*In 0.10 to 4.00*In step 0.01*In
This setting determines the new pick-up setting for second stage earth fault element during the tclp time delay.
This setting determines the new operating time delay for the second stage definite time element during the tclp time.
41. IN2>2 TMS 0.1 0.025 to 1.2 step 0.005
This setting determines the new time multiplier setting to adjust the operating time of the IEC / UK IDMT characteristic during the t
42. IN2>2 Time Dial 1 0.01 to 100 step 0.01
This setting determines the new time multiplier setting for the second stage derived earth fault element to adjust the operating time of the
IEEE / US IDMT characteristic during the tclp time.
43. IN2>3 Status Enabled Blocked / Enabled
The IN2>3 status cells have two setting options, "Enabled" and "Blocked". Selecting "Enabled" for a particular stage means that the
current and time settings programmed in the following cells will be adopted during the "tclp" time. Selecting "Blocked" simply blocks the
relevant protection stage during the "tclp" time. It also removes the following current and time settings for that stage from the menu.
44. IN2>3 Current Set 0.20*In 0.10 to 4.00*In step 0.01*In
This setting determines the new pick-up setting for third stage earth fault element during the tclp time delay.
45. IN2>3 Time Delay 0.01 S 0s to 200s step 0.01s
This setting determines the new operating time delay for the third stage definite time element during the tclp time.
This setting determines the new time multiplier setting to adjust the operating time of the IEC IDMT characteristic during the tclp time.
47. IN2>3 Time Dial 1 0.01 to 100 step 0.01
This setting determines the new time multiplier setting for the third stage derived earth fault element to adjust the operating time of the
IEEE / US IDMT characteristic during the tclp time.

This setting determines the tripping characteristic for the first stage Negative sequence overcurrent element.
2. I2>1 Current Set 1.00*In
If DT 0.10 to 35.00*In step 0.01*In
If IDMT 0.10 to 4.00*In step 0.01*In
This setting determines the pick-up setting for first stage Negative sequence overcurrent element.
This setting determines the time-delay for the definite time setting if selected for first stage Negative sequence overcurrent element.
4. I2>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.
