3.2. CT/VT Config

Description
Phase Nom Voltage
Selects the nominal voltage setting Vn of the voltage input
Phase Voltage Trim Magnitude
Allows trimming of voltage magnitude, the setting value should
be the voltage required to be added to get back to Phase Nom
Voltage.
Phase Voltage Trim Angle
Allows trimming of voltage angle, the setting value is added to
the current voltage angle
Phase Voltage Config
Required to allow for different types of physical VT connections.
Phase VT Ratio Prim
Phase VT Ratio Sec
Vx Nom Voltage
Selects the nominal voltage setting Vn of the voltage input
Vx Voltage Trim Magnitude
Allows trimming of voltage magnitude, the setting value should
be the voltage required to be added to get back to Vx Nom
Voltage.
Vx Voltage Trim Angle
Allows trimming of voltage angle, the setting value is added to
the current voltage angle
Vx VT Ratio Prim
Vx VT Ratio Sec
Phase Current Input
Selects whether 1 or 5 Amp terminals are being used for phase
inputs
Phase CT Ratio Prim
Phase CT ratio to scale primary current instruments
Phase CT Ratio Sec
