20020122 This revision includes the following changes:
Appendix A:
− Updated Firmware Version information.
20011219 This revision includes the following changes:
− Reissued entire manual.
− Most of the following manual changes for this revision are due to the addition
of the 0.2 A nominal neutral channel (IN) current input option. This option
provides ground directional control for low-impedance grounded, Petersen
Coil grounded, and ungrounded/high-impedance grounded systems (see
Table 4.1).
Section 1:
− Added 300 Vac wye-connected voltage input information to Table 1.2:
SEL-351 Firmware Versions.
− Added information on the following to the General Specifications subsection:
0.2 A nominal neutral channel (IN) current input option, frequency tracking
with positive-sequence voltage V
1
(when V
A
not available), 220 Vdc
optoisolated inputs, extended lower end of pickup setting range for residual
ground overcurrent elements, and changed meter specification for currents I
A
,
I
B
, and I
C
.
Section 2:
− Changed Figure 2.4 to a vertical panel-mount example.
− Added connection diagrams (Figures 2.14 through 2.16) for high-impedance
or low-impedance grounded, Petersen Coil grounded, and ungrounded
systems.
