4.6.5 CT / VT Settings
It is the display of current and voltage transformers that provide current and voltage
information to the device and how phase transforms of voltage transformers are selected. CT /
VT Settings are located on the device under Main Menu> Configuration Settings> CT / VT
Settings. The setting the menu is as follows.
• VT Connection
Used to indicate which of the voltage transformer terminals connected to the relay. This
rotation; 3 Phase-Neutral (3Vpn), 2 Phase-Phase + Residual voltage (2Vpp + Vr) or 2 Phase-
Neutral + Residual voltage (2Vpn + Vr) can be selected.
• Phase VT Primer
The voltage transformer connected to the device is the screen where the primary phase
voltage is assigned. This setting is in the range of (0.1 - 1000) kV.
• Phase VT Secondary
The voltage transformer connected to the device is the display where the secondary phase
voltage is assigned. This setting is made in the (2 - 130) V range.
• Residual VT Primer
