The
FLEXELEMENT 1 HYSTERESIS
setting defines the pickup–dropout relation of the element by specifying the width of the
hysteresis loop as a percentage of the pickup value as shown in the
FlexElement direction, pickup, and hysteresis
diagram.
The
FLEXELEMENT 1 DT UNIT
setting specifies the time unit for the setting
FLEXELEMENT 1 dt
. This setting is applicable only if
FLEXELEMENT 1 COMP MODE
is set to “Delta”. The
FLEXELEMENT 1 DT
setting specifies duration of the time interval for the
rate of change mode of operation. This setting is applicable only if
FLEXELEMENT 1 COMP MODE
is set to “Delta”.
This
FLEXELEMENT 1 PKP DELAY
setting specifies the pickup delay of the element. The
FLEXELEMENT 1 RST DELAY
setting
specifies the reset delay of the element.

BASE
= PhaseVTSecondary / PhaseCTSecondary, where PhaseVTSecondary and
PhaseCTSecondary are the secondary nominal voltage and the secondary nominal current of the
distance source. In case multiple CT inputs are summed as one source current and mapped as
the distance source, use the PhaseCTSecondary value from the CT with the highest primary
nominal current.
Distance source is specified in setting under
SETTINGS > GROUPED ELEMENTS > SETTING
GROUP 1(6) > DISTANCE
.
PhaseVTSecondary and PhaseCTSecondary are specified in setting under
