IPR96D Ground Protection Relay
6.4
Instruction Manual: IPR96D GBM 24/11/2020
Ground Protect.
Ground Timed2 O/C
Pickup
Value
12 %CT
RANGE: 1
300
STEPS: 1
Enter the ground overcurrent pickup level. This level determines the current level
at which the relay will start counting the circuit breaker/disconnector trip time
according to the protection curve selected in the following line:
GROUND O/C
CURVE
.
[6.4
Setpoints: GROUND PROTECT.
]
If Ground Timed2 O/C Relay
≠
- - -
Ground Protect.
Ground O/C Curve
Value
ANSI MOD INV
RANGE: ANSI EXTREME INV; ANSI VERY INV; ANSI NORMAL INV; ANSI MOD
INV; DEFINITE TIME; IEC-C EXTREME INV; IEC-B VERY INV; IEC-A NORMAL
INV; IEC SHORT TIME; IAC EXTREME INV; IAC VERY INV; IAC NORMAL INV;
IAC MODERATE INV
Enter the ground 2 overcurrent protection curve shape required.

If Ground Timed2 O/C Relay
≠
- - -
Ground Protect.
Ground Timed2 O/C
Delay
Value
1.00 s
RANGE: 0.01
600
STEPS: 0.01, 0.1, 1
Enter the ground timed 2 overcurrent delay. The related output will activate if the
current rating is superior to “GROUND TIMED O/C PICKUP” for a longer time than
the set one.

If Ground O/C Curve = DEFINITE TIME
and
≠ - - -
Ground Protect.
Ground Timed2 O/C
Mult.
Value
1.0
RANGE: 0.1
20.0
STEPS: 0.1
Set the ground overcurrent multiplier for the selected curve.

Ground Protect.
Ground Inst. O/C
Relay
Value
- - -
RANGE: NONE; ANY COMBINATION OF TRIP, AUX1 OR AUX2.
Select the outputs to be activated by the ground instantaneous overcurrent
protection (ANSI 50N).
Ground Protect.
Ground Inst. O/C
Pickup
Value
120 %CT
RANGE: 1
2000
STEPS: 1, 10
Enter the instantaneous overcurrent pickup level. This level determines the
current level at which the relay will start counting the time for the activation of the
related output.

If Ground Inst. O/C Relay
≠
- - -
Ground Protect.
Ground Inst. O/C
Delay
Value
0 ms
RANGE: 0
2000
STEPS: 10
Enter the intervention delay for ground instantaneous overcurrent protection.
If: the ground current increases above the value entered in “GROUND INST. O/C
PICKUP” for a time > delay time selected, the output will activate.

Value
NONE
RANGE: ACTIVATE AUX2; ACTIVATE AUX1; EXTERNAL RESET; BREAKER
STATUS; NONE
Select the function to be associated with INPUT 1.
