Seq.I>1 DT = 0
Assign Seq.I>1 trip function in Output relay (J OUT1).
There are two stages simulated through the power system simulator for the prefault and fault
simulation, the first stage is normal condition for 500 milliseconds and second stage is fault
condition for 200 milliseconds as given below.
And the above condition, The Seq.I>1 elements is operated when the Positive sequence current
exceeded the pickup value and relevant feedback is received in power system simulator and
stopped the current injection. The relevant Waveforms are recorded and it can be analyzed by
using the DR analysis software. Analogue and Digital channels should be recorded with pre fault
and post fault conditions. Waveform can be exported to COMTRADE format.
