OC-W-79 LOGIC SCHEME
Logic scheme OC-W-79 is intended for feeder breaker applications where nondirectional overcurrent
protection is required. Automatic reclosing is included and is initiated by a protective overcurrent trip or by
an external contact to initiate reclosing (RI). Breaker failure and other control functions such as virtual
switches are not provided in this scheme.
The components of OC-W-79 logic are summarized in Tables 8-5, 8-6, 8-7, and 8-8.
Figure 8-3 shows a
one-line drawing for the OC-W-79 logic scheme. A diagram of OC-W-79 logic is shown in
Figure 8-4.
