Permissive underreaching transfer tripping (PUTT)
The criteria for tripping and transmission of a transfer trip signal by the distance protection
function in a PUTT scheme are given in the tabular overview below.
t = Delay (1)
= 0 sec :
t = Com Rec :
t = Delay (2) :
t = Delay (3) :
t = Delay (Def) :

PUTT transmit logic (PUTT_SEND)
The logic (PUTT_SEND) transfers its output signals to a common transmit logic for PUTT,
POTT and BLOCK OR schemes.
