Remote 2
Phase A, B, C, and Ground current (Primary)
These indicate the current measured at the remote 2 relay for each of the relay inputs. The
measurements are in A
RMS
and are referenced to the primary side of the CT.
Phase A differential, operate and restraint current (Sec)
These indicate the differential, operate and restraint currents calculated at the local relay for phase A.
The measurements are in A
RMS
and are referenced to the secondary side of the CT.
Phase B differential operate and restraint current (Sec)
These indicate the differential, operate and restraint current calculated at the local relay for phase B.
The measurements are in A
RMS
and are referenced to the secondary side of the CT.
Phase C differential operate and restraint current (Sec)
These indicate the differential, operate and restraint current calculated at the local relay for phase C.
The measurements are in A
RMS
and are referenced to the secondary side of the CT.
Ground differential operate and restraint current (Sec)
These indicate the differential, operate and restraint current calculated at the local relay for ground.
The measurements are in A
RMS
and are referenced to the secondary side of the CT.
