Measured voltage parameters will be displayed here. The V/Hz measurement is a per unit value based on Vab voltage/
measured frequency divided by VT nominal/nominal system frequency. Polar coordinates for measured phase and/or line
voltages are also shown using Va (wye connection) or Vab (open delta connection) as a zero angle reference vector. In the
absence of a voltage signal (Va or Vab), IA output current is used as the zero angle reference vector.
