Figure 2.4.4.4 Echo Function in DEF POP and DEF UOP Scheme Logic
Figure 2.4.4.5 shows the scheme logic of the weak infeed trip function. Weak infeed tripping is
executed on condition that a trip permission signal has been received (ECHO1_DEF-R1=1) for
the POP, the undervoltage element UVL (UVLS or UVLG) operates.
The undervoltage element responds to three phase-to-phase voltages and three phase-to-ground
voltages. The undervoltage element prevents false weak infeed tripping due to spurious operation
of the channel.
Single-phase tripping or three-phase tripping is also applicable to weak infeed tripping according
to the reclosing mode of the autoreclose function.
The weak infeed trip function can be disabled by the scheme switch [WKIT] and the PLC signal
WKIT_BLOCK.

Figure 2.4.4.5 Weak Infeed Trip Logic
When the signaling channel of DEF POP or DEF UOP is separated from that of distance command
protection, the signal S-DEF2 is used for CS and assigned to a user configurable binary output
relay (see Section 3.2.2.).
