MENU TEXT
Setting for the tripping characteristic for the second stage earth fault overcurrent element.
IN>2 Directional
This setting determines the direction of measurement for first stage element.
IN>2 Current Set
Pick-up setting for second stage overcurrent element
IN2>1 IDG Is
This setting is set as a multiple of "IN>" setting for the IDG curve (Scandinavian) and determines the actual IED current threshold at which the
element starts.
IN>2 Time Delay
Setting for the time-delay for the definite time setting if selected for second stage element. The setting is available only when DT function is
selected.
IN>2 TMS
Setting for the time multiplier setting to adjust the operating time of the IEC IDMT characteristic.
IN>2 Time Dial
Setting for the time multiplier setting to adjust the operating time of the IEEE/US IDMT curves. The Time Dial (TD) is a multiplier on the
standard curve equation, in order to achieve the required tripping time. The reference curve is based on TD = 1.
Care: Certain manufacturer's use a mid-range value of TD = 5 or 7, so it may be necessary to divide by 5 or 7 to achieve parity.
IN2>1 IDG Time
Setting for the IDG curve used to set the minimum operating time at high levels of fault current.
IN>2 Reset Char
Setting to determine the type of reset/release characteristic of the IEEE/US curves.
IN>2 tRESET
Setting that determines the reset/release time for definite time reset characteristic.
IN>3 Status
Setting that defines third stage overcurrent operating status. Depending of this setting, IN>3 will be enabled permanently or in case of
Voltage Transformer Supervision (fuse fail) operation
