4.3
Phase overcurrent (I> and I>>)
Set the various thresholds on the trip output (refer to User Guide). For
MiCOM P120
, the
same test can be performed for the phase/or earth threshold.
4.3.1
Test wiring diagram
This test wiring diagram makes it possible to conduct tests relating to the I> and I>>
thresholds.
The diagram describes current injection onto the 5 Amp phase current inputs (terminals 41-
42, 43-44, 45-46). To carry out injection for the 1 Amp phase inputs, perform the same test
on the 1 Amp inputs (terminals 49-50, 51-52, 53-54).
