Figure 171:
Example of 67NIEF operation in ”Intermittent EF” mode in the faulty
feeder, Peak counter limit=3
The timer calculates the pickup duration value PICKUP_DUR which indicates the
percentage ratio of the start situation and the set operating time. The value is available in
the monitored data view.
Timer 2
If the function is used in the directional mode and an opposite direction transient is
detected, the
BLK_EF
output is activated for the fixed delay time of 25 ms. If the
PICKUP
output is activated when the
BLK_EF
output is active, the
BLK_EF
output is deactivated.
Blocking logic
There are three operation modes in the blocking function. The operation modes are
controlled by the
BLOCK
input and the global setting
Configuration/System/Blocking
mode
which selects the blocking mode. The
BLOCK
input can be controlled by a binary
input, a horizontal communication input or an internal signal of the protection relay's
program. The influence of the
BLOCK
signal activation is preselected with the global
setting
Blocking mode
.
