Protection stages
5.3.1.
Overcurrent protection stages
Overcurrent stage I> (50/51)
Setting range
0.10 – 4.00 x I
gn
Definite time function:
- Operating time
0.08 – 300.00 s (step 0.02 s)**
IDMT function:
- 4 curve groups (IEC 60255-3)
EI, VI, NI, LTI *)
- Time multiplier T
p
0.05 – 3.20
Start time
<60 ms
Reset time
<60 ms
Reset ratio
0.97
Inaccuracy:
- Starting
±2% of set value
- Operate time at definite time function
±1% or ±30 ms
- Operate time at IDMT function
±5% or at least ±30 ms (I< 50 x I
n
and I< Iset
*20)
*) EI = Extremely Inverse, NI = Normal Inverse, VI = Very Inverse, LTI = Long Time Inverse
**) This is the instantaneous time i.e. the minimum total operational time including the fault
detection time and operation time of the trip contacts.
Overcurrent stage I>> (50/51)
Setting range
