FIGURE 21 - LOGIC DIAGRAM FOR THE POP Z2 SCHEME
(SEE TRIP LOGIC TABLE IN SECTION 2.8.2.4)
2.9.2.2
Permissive Overreach Protection with Overreaching Zone 1 (POP Z1)
This scheme is similar to that used in the AREVA EPAC and PXLN relays. Figure 22 shows
the zone reaches, and Figure 23 the simplified scheme logic. The signalling channel is
keyed from operation of zone 1 elements set to overreach the protected line. If the remote
relay has picked up in zone 1, then it will operate with no additional delay upon receipt of this
signal. The POP Z1 scheme also uses the reverse looking zone 4 of the relay as a reverse
fault detector. This is used in the current reversal logic and in the optional weak infeed echo
feature.
NOTE:
Should the signalling channel fail, the fastest tripping in the Basic
scheme will be subject to the tZ2 time delay.
Send logic:
Zone 1
Permissive trip logic:
Zone 1 plus Channel Received.
