Per Phase Voltage Present Indicators
For Form 12S meters, the display can indicate the status of phase A and
phase C voltages.
■ If phase A and phase C voltages are at or above 50 V, the display will
indicate that both voltages are present (see Figure B-8).
■ If the phase C voltage is not present (phase C is less than 50 V), the
display will indicate that only phase A voltage is present (see
Figure B-9).
■ If phase A and phase C voltages are below 50 V, the display will indicate
that neither voltage is present (see Figure B-10).
