display. The relay also adjusts the phase angle of the measured phase-
to-neutral voltage by ±30º to represent phase-to-phase voltage. The
relay displays zero for the magnitudes of the unmeasured voltages.
Balanced voltages are assumed for power and power factor
calculations.
Relays that are not equipped with phase voltage inputs hide these settings and
disable voltage-based protection and metering functions.
