As shown in Figure 2.20-4, the OCMFS element can operate when one or more detectors
keep operating for five seconds. The OCMFS operation will reset when all LD detectors are
reset.
(ii)
Setting of OCMF
The OCMF function is used for tripping, but it can be used for the OST alone by scheme switch
[
OCMFS-EN
]. When
On-T
is set, it operates for the trip function, whereas it will operate for
the OST alone if
On-S
is set for the [
OCMSF-EN
].
Off
has to be set for the [
OCMSF-EN
], if the
operation of the OCMF function should be disabled.
2.20.5
Under-voltage element for phase-to-earth (UVFS)
Its element can measure a voltage of phase-to-earth. Its sensitivity is determined with setting
[
UVFS
]. Its operation is initiated if a phase-to-earth voltage are below the setting.
On
has to
be set for the scheme switch [
UVFS-EN
] for its operation and setting.
2.20.6
Under-voltage element for phase-to-phase (UVSFS)
Its element operates if a voltage of phase-to-phase is below setting [
UVSFS
].
On
has to be set
for the scheme switch [
UVSFS-EN
] for its operation and setting.
2.20.7
Under-voltage change detection element (DUVFS)
Its element operates if a voltage is below setting [
DUVFS
]. Its operation is decided by the
comparison between a present voltage and a previous (i.e., 1 cycle before) voltage. Its
sensitivity is determined by the setting [
DUVFS
], and its off-delay timer is provided by the
setting [
TDUVFS
].
