            Measurement value as in the following format depending on value of measurand:
             - voltmagnitude: phase-to-ground RMS value, unit volts
             - voltangle: unit radian
             - currmagnitude: RMS value, unit ampere
             - currangle: unit radian
             - activepower: single phase power, unit watts
             - reactivepower: single phase power, unit voltampere reactive
             - apparentpower: single phase power, unit voltampere
             - frequency: unit hertz
