Functions
2.3 Directional Overcurrent Protection 67, 67N
Interaction with Automatic Reclosing Function (ground)
If reclosing follows, high-speed and simultaneous closing in the event of a fault with 67N-2 is usually desired.
If the fault still exists after reclosing, the 67N-1 or 67N-TOC element is initiated with graded tripping times,
that is, the 67N-2 or 67N-3 element is blocked. For this purpose, parameter 1614 67N-2 active or 1632
67N-3 active is used to determine whether the 67N-2 or 67N-3 element is influenced by the release signal
of the internal or an external automatic reclosing device or not. The setting with 79 active means that the
67N- 2 or 67N-3 element is only released if the automatic reclosing function is not blocked. If this is not
desired, the setting always is selected so that the 67N-2 or 67N-3 element is always active as configured.
The integrated automatic reclosing function of 7SJ62/64 also provides the option to individually determine for
each overcurrent element whether tripping or blocking is to be carried out instantaneously, unaffected by the
AR with time delay (see Section
2.3.11
