2.4.2 PHASE(50P1, 50P2)
MIFII provides 2 phase instantaneous overcurrent elements, 50P1 (‘H’ for high pickup) and 50P2 (‘L’ for low pickup). Each
one can be enabled/disabled and set independently. Settings from these elements allow to set the pickup value from 0.1 to
30 times the rated current, and the time delay from 0.00 to 600.00 seconds.
2.4.3 GROUND TIME OVERCURRENT ELEMENT (51G)
The Ground Time Overcurrent element offers the same setting possibilities as the Phase Time Overcurrent element. The
ground current can be obtained from a residual connection on the CTs. For a more sensitive ground current detection, a
window type (zero sequence) CT, taking the three phases inside its windows can be used. Refer to figure 3-6 for more
details.

The MIFII relay provides 2 Ground Instantaneous Overcurrent Elements, 50G1 (‘1’ for High pickup) and 50G2 (‘2’ for Low

Overcurrent Elements, 50P1 and 50P2.
