Default Description
- Three phase group signal for voltage inputs
0 Block of function
0 A signal that indicates a forward fault has been detected
and will block tripping if there was a pre-existing reverse
fault condition (IREV)
0 A signal that indicates a reverse fault has been detected
and activates current reverasl logic
0 Block of WEI logic
0 Block of WEI logic due to operation of other protections
that would effect a pilot trip or the detection of reverse
faults that will be tripped by an external device
0 Block of trip from WEI logic through the loss of voltage
(fuse-failure) function
0 Block of trip from WEI logic by an open breaker
0 POTT or Unblock carrier receive for WEI logic
Description
Operation of current reversal logic
Trip of WEI logic
Trip of WEI logic in phase A
Trip of WEI logic in phase B
Trip of WEI logic in phase C
A signal that indicates channel start (CS) by WEI logic
Default Description
Disabled Operating mode of Current Reversal Logic
0.020 Pickup time for current reversal logic
0.060 Time Delay to prevent Carrier send and local
trip
