:
• Set \ Profile A (or B) \ Breaker failure - BF side H
• Set \ Profile A (or B) \ Breaker failure - BF side L
For every threshold the following block criteria are available:
Logical block (Block1)
If the DthAL1BLK1,DthAL2BLK1and/or Dth>BLK1 enabling parameters are set to ON and a
binary input is designed for logical block (Block1), the concerning element is blocked off whenever
the given input is active.
5
The enabling parameters are available inside the Set \ Profile A (or B)\
Thermal image-49 \ DthAL1 Element (DthAL2 Element, Dth> Element) menus, while the Block1 fun-
ction must be assigned to the selected binary input inside the Set \ Board 1(2) inputs \ Binary input
IN1-1...(IN1-x) menus.
Selective block (Block2)
All along the protective elements the selective block may be set.
The logic selectivity function may be performed by means any combination of the following I/O:
• One committed pilot wire input (BLIN1).
• One or more binary inputs designed for input selective block.
• One committed pilot wire output (BLOUT1).
• One or more output relays designed for output selective block.
Only when the committed pilot wire are used the continuity check of the pilot wire link is active.
Use of committed pilot wire input BLIN1:
• The protection is blocked off according the selectivity block criteria when the input BLIN1 is active.
The information about phase or phase+earth block may be select programming the ModeBLIN1
parameter inside the Set \ Profile A (or B) \ Selective block-BLOCK2 \ Selective block IN menus.
Use of binary inputs:
• If the DthAL1BLK2IN,DthAL2BLK2INand/or Dth>BLK2IN parameter are are set to ON and
a binary input is designed for selective block (Block2), the protection is blocked off by phase ele-
ments (Block2 Iph) or by any protection element (Block2 Iph/IE) according the selectivity block
criteria.
6
The enable DthAL1BLK2IN, DthAL2BLK2IN and/or Dth>BLK2IN parameters are
available inside the Set \ Profile A (or B) \ Thermal image-49LT \ DthAL1 Element, DthAL2 Element,
Dth> Element menus, while the Block2 Iph and
Block2Iph/IE functions must be assigned to
the selected binary inputs inside the Set \ Board 1(2) inputs \ Binary input IN1-1...(IN1-x) menus.
Use of committed pilot wire output BLOUT1:
• The information about phase or phase+earth block may be select programming the ModeBLOUT1
parameter inside Set \ Profile A (or B) \ Selective block-BLOCK2 \ Selective block OUT menus.
Use of output relay:
• If the DthAL1BLK2OUT,DthAL2BLK2OUTand/oDth>BLK2OUT enable parameters are set
to ON and a output relay is designed for selective block (Block2), the protection issues a block
output by phase elements (BLK2OUT-Iph) or by any protection element (BLK2OUT-Iph/IE), whene-
ver the given element (DthAL1, DthAL2 e/o Dth>) becomes active. The enable
DthAL1BLK2OUT,
DthAL2BLK2OUT and/or Dth>BLK2OUT parameters are available inside the Set \ Profile A
(or B) \ Thermal image-49LT \ DthAL1 Element (DthAL2 Element, Dth> Element) menus, while the
BLK2OUT-Iph-K,BLK2OUT-Iph/IE-Kand/or BLK2OUT-IE-Koutput relays must be set insi-
de the Set \ Profile A (or B) \ Selective block-BLOCK2 \ Selective block OUT menus.
Internal selective block (Block4)
As well as to send or transmit a selective block toward other protective relays, each protective
element may be enabled for receive or transmit a selective block from/to other internal protective
elements.
7
The internal selective block of one or more element concerning the thermal image function may
be enabled/disabled by means the DthAL1BLK4, DthAL2BLK4, and/or Dth>BLK4 parameters
(virtual input and output common to all protective thresholds); the following operating modes are
available:
• IN - the element is enabled to receive the selective block from an internal input.
• OUT - the element is enabled to send the selective block to an internal output.
• OFF - the element is disabled to send/receive the internal selective block.
Transmission and reception for the same element is not allowed, so any stall situation due to wrong
setting is avoided.
The internal selective block can work together with an external selective block from other protective
relays (Block2).
