4.2 Signal list
4.3 Setting table
IN:
DESCRIPTION:
FUSE-MCB
Functional input sigal, which is normally connected via binary input to the auxiliary NC
contact of the miniature circut breaker in the voltage measuring circuits
FUSE-DISC
Functional input signal, which is normally connected via binary input to the auxiliary NC
contact of the line disconnector
OUT:
DESCRIPTION:
FUSE-VTSU
Output information on the operation of the FFS function. It is supposed to block all voltage
dependent functions within the terminal, except the distance protection. Configure it for
these purposes to the blocking inputs of the relevant functions.
FUSE-VTSZ
Output information on the operation of the FFS function. Its appearence is controlled by
the voltage/current check function. It should block the operation of distance protection
function during fuse-failure conditions in the voltage measuring circuits.
FUSE-VTF3PH
Output signal, which appears five seconds after the fuse-failure condition is detected if the
measured voltages in all three phases are low.
PARAMETER SETTING RANGE
DESCRIPTION
Operation
Off / Zeroseq / Nega-
tiveseq
Operating mode of the fuse-failure supervision function. The opera-
tion can be inhibited or based on measurement of the zero or negative
sequence quantities.
U>
(10-50)% of Ur/sqr(3)
The operating level of the voltage measuring element for the zero
sequence (3.U
0
) or negative sequence (3.U
2
) voltage, set as percent-
age of the terminal rated phase voltage.
I>
(10-50)% of Ir
The operating level of the current measuring element for the zero
sequence (3.I
0
) or negative sequence (3.I
2
) current, set as percentage
of the terminal rated current.
