2.11.1
Stub-OC characteristic
The characteristic of the stub-OC element is shown as a circle that has a center at the origin,
as shown in Figure 2.11-2. The user can set the threshold value of the stub-OC element using
setting [
OCSTUB
]. The STUB-OC function can operate when the user set scheme switch
[
STUB
]
On
.

Scheme logic
Figure 2.11-3 shows the stub-OC logic; the stub-OC function can issue trip signals during the
DS being opened (i.e., logic signal ‘DS_OPEN’ = 1 (TRUE1)).

] is provided in order that the OCSTBU element should
be blocked when second-harmonic frequency components (2f) are detected on the flowing
