9.3.2.5
Restricted earth fault protection REFPDIF
Main menu/Settings/Setting group N/Differential protection/
LowImpREF(PDIF,87N))/REF
Displays available instances of REFPDIF with some settings per instance. These
are for the Current transformer ratios, operation, rated current
Ibase
operate angle
of the zero sequence directional feature and
Idmin
which is a percentage of
Ibase
and is the current threshold in section one of the characteristic slope.
9.3.2.6
High impedance differential protection HZPDIF
Main menu/Settings/Setting group N/Differential protection/
HighImpDifferential(PDIF,87)/HZD
Displays available instances of HZPDIF with settings for operation, the alarm
voltage level [V] on the CT secondary side, the time delay to activate the alarm, the
operating voltage level [V] on the secondary side of the CT and the value of the
series resistor in [Ω].
9.3.3
Impedance protection
9.3.3.1
Overview
Under Impedance protection there are settings for Distance zones, Phase selection,
directional impedance, Power swing detection, and Automatic switch onto fault
protection. Each instance of a function can be switched on or off with the operation
parameter and the remaining parameter settings like rated current and voltage are
data required for the function to operate.
9.3.3.2
Full-scheme distance protection, mho characteristic ZMHPDIS
Main menu/Settings/Setting group N/Impedance Protection/
MhoDistance(PDIS,21)/ZMH
Displays available adjustable parameters. These include the impedance and timer
settings.
9.3.3.3
Directional impedance element for mho characteristics ZDMRDIR
Main menu/Settings/Setting group N/Impedance protection/Directional
Impedance/ZDM
Includes settings for base current, voltage and impedance direction angles.
