The phase direction control in following four settings should be enabled.
GROUP # / DIRECTION / PHASE / Type
Range NONE, FORWARD, REVERSE
Default
NONE
Step
~
Set phase direction type.
NONE : Regardless of phase direction, phase fault and overcurrent are
detected by normal phase current(Ia,Ib,Ic).
FOR : Phase fault and (+) Phase overcurrent are detected when
forward phase direction.
(-) Phase overcurrent is detected when reverse phase direction.
REV : Phase fault and (+) Phase overcurrent are detected when reverse
phase direction.
(-) Phase overcurrent is detected when forward phase direction.
GROUP # / DIRECTION / PHASE / Type
Range
0 ~ 359 degree
Default 300 Step 1 degree
Enter the Maximum Torque Angle. The Maximum Torque Angle
setting determines the range of current direction for the polarizing
voltage.
For typical distribution systems, the faulted angle of the phase will be
approximately
∠
300
∼∠
330 degree.
GROUP # / DIRECTION /PHASE / M.P.V(V1)
Range 0(OFF), 0.10~0.80 xVT
Default 0.30 Step 0.01 xVT
To check Phase disconnect direction, it shall set Minimum Polarizing
Voltage, V
1
). It is available to check the direction when a voltage shall
be more than this set value. Otherwise, checking is blocked. In case of
setting 0(OFF), direction is not checked.
