The ACM100 uses these PGN to transmit voltage, frequency, and current information
Field 1: Line-Line AC RMS Voltage – This field indicates the AC RMS voltage between this
phase and the next phase in units of 1 V.
2: Line-Neutral AC RMS Voltage – This field indicates the AC RMS voltage between
this phase and the neutral phase in units of 1 V.
3: AC Frequency – This field indicates the frequency of the AC voltage in units of 1/128
Hz.
4: AC RMS Current (not transmitted for the “Bus” AC Source Type) – This field indicates
the current flowing through the specified phase in units of 1 A.
PGN 65006 – Utility Phase C AC Reactive Power
PGN 65009 – Utility Phase B AC Reactive Power
PGN 65012 – Utility Phase A AC Reactive Power
PGN 65015 – Utility Total AC Reactive Power
PGN 65019 – Generator Phase C AC Reactive Power
PGN 65022 – Generator Phase B AC Reactive Power
PGN 65025 – Generator Phase A AC Reactive Power
PGN 65028 – Generator Total AC Reactive Power
The ACM100 uses this PGN to transmit reactive power and power factor information.
Field 1: Reactive Power – This field indicates the reactive power delivered by the source in
units of 1 VAr.
2: Power Factor – This field indicates the magnitude of the power factor supplied by the
source in units of 1/16384 (dimensionless).
3: Power Factor Lagging – This field indicates whether the specified power factor is
lagging or leading.
