CHARACTERISTICS
With inputs from sensors versions, the type of measurement of line-to-line voltages and phase volt-
ages may be select: the
Utype59Uavg
parameter in the
Set \ Profi le A(or B) \ Average overvoltage-
59Uavg \ Common confi gurations
menu may be set. The possible settings are
Uph-ph
(voltages) or
Uph-n
(phase voltages).
The element can be disabled in the case of connection of the measuring inputs (TV or TV-I-NI) down-
stream of the Device Interface when the DI is open.
The threshold disabling is selected by setting
ON
the
Uavg>disbyCB_OPEN
parameter, inside the
Set \ Profi le A(or B) \ Average overvoltage-59Uavg \
Uavg> Element \ Setpoints
menu.
Breaker failure (BF)
The average overvoltage element can produce the Breaker Failure output if the
Uavg> BF
param-
eter is set to
ON.
The parameter is available inside the
Set \ Profi le A(or B) \ Average overvoltage - 59Uavg \
Uavg> Element \ Setpoints
menus.
Logical block (Block1)
If the
Uavg>BLK1
enabling parameter is set to
ON
and a binary input is designed for logical block
(Block1), the protection is blocked off whenever the given input is active.
The trip timer is held in reset condition, so the operate time counting starts when the input block goes
down. The enabling parameters are available inside the
Set \ Profi le A(or B) \ Average overvoltage
- 59Uavg \
Uavg> Element \ Setpoints
menus, while the
Block1
function must be assigned to the
selected binary input inside the
Set \ Inputs \ Binary input IN1(x)
menus (IN1 or INx matching)
.
All the parameters can be set separately for
Profi le A
and
Profi le B
.
