6.3. Line VL Sensing
6.3.1. Description
To measure Load Voltage, set Connect Type, 2nd
Nominal Voltage, VT Ratio.
With Line VTs installed, the EVRC2A can be used to perform synchronism elements.
6.3.2. Setting
PRIMARY SETTING / SYSTEM SETUP / LINE VL SENSING / Connect Type
Range
NONE, WYE, DELTA, VD-W, VD-D
Default
VD-W
Step
~
Enter None if line VTs are not to be used.
NONE :
VT uninstalled.
If used, external PT by user, enter the VT connection made to the
system as Wye or Delta.
WYE :
Install type wye.
DELTA :
Install type delta.
If installed VT of Capacitor Voltage Divide type.
VD-W :
If the user system made to 3 phase 4 wire.
VD-D :
If the user system made to 3 phase 3 wire.
PRIMARY SETTING / SYSTEM SETUP / LINE VL SENSING / VT 2nd(v)
Range
30.0 ~ 250.0 V
Default
100.0
Step
0.1 V
Enter Secondary Nominal Voltage(V)
This setting is the voltage across the VT secondary winding when
nominal voltage is applied to the primary.

Default
155.9
Step
0.1
Enter the VT primary to secondary turns-ratio with this setting.
