Figure 5-28: clock signal suring reclose cycle
Figure 5-29: Reclose initiation and block signals configuration example shows an example of the autoreclose initiation and
protection element block signals after the different trips. The autoreclose initiate signal is configured to the relay general
trip that corresponds to virtual output 83 configured in the logic configuration tool, and a physical contact to generate an
external autoreclose initiation.
In the example shown on the figure, the 50PH element block signal is configured as a combination of block by digital input,
block by non-trip permission of the directional element, and finally the element remains blocked during the reclosing
cycle. This means that only the first trip can be executed by the phase instantaneous overcurrent element; after the first
reclose trip, the element remains blocked until the end of the cycle.
