Single Shot Protection Settings

Single Shot mode uses dedicated protection settings for each configured element which can be more appropriate to the situation. For example, closing onto a fault would normally warrant a fast tripping time.

Single Shot settings for OC, EF, SEF, and NPS protection can be configured in the same manner as for Trips 1, 2, 3, and 4. The OC, EF, SEF, and NPS Single Shot Protection trip settings can be selected individually via separate protection pages. Each page is similar to the normal protection trip setting pages.

In WSOS the Single Shot settings can be configured on the Single Shot page.

Single Shot settings can also be configured on the operator interface.

If the ACR trips in Single Shot mode it generates a Single Shot event preceded by Active Protection Group and Fault Type events.
