The metered values for real, reactive, and apparent power, as well as power factor, are displayed in this menu. The "SRC
1" text will be replaced by whatever name was programmed by the user for the associated source (see
SETTINGS ÖØ SYS-
TEM SETUP
ÖØ SIGNAL SOURCES).
g) FREQUENCY METERING
PATH: ACTUAL VALUES ÖØ METERING Ö SOURCE SRC 1 ÖØ FREQUENCY
The metered frequency values are displayed in this menu. The "SRC 1" text will be replaced by whatever name was pro-
grammed by the user for the associated source (see SETTINGS ÖØ SYSTEM SETUP ÖØ SIGNAL SOURCES).
SOURCE FREQUENCY is measured via software-implemented zero-crossing detection of an AC signal. The signal is either a
Clarke transformation of three-phase voltages or currents, auxiliary voltage, or ground current as per source configuration
(see the SYSTEM SETUP ÖØ POWER SYSTEM settings). The signal used for frequency estimation is low-pass filtered. The
final frequency measurement is passed through a validation filter that eliminates false readings due to signal distortions and
transients.
6.3.3 SYNCHROCHECK
PATH: ACTUAL VALUES ÖØ METERING ÖØ SYNCHROCHECK Ö SYNCHROCHECK 1(2)
The actual values menu for synchrocheck 2 is identical to that of synchrocheck 1. If a synchrocheck function setting is "Dis-
abled", the corresponding actual values menu item will not be displayed.
6.3.4 TRACKING FREQUENCY
PATH: ACTUAL VALUES ÖØ METERING ÖØ TRACKING FREQUENCY
The tracking frequency is displayed here. The frequency is tracked based on the selection of the reference source with the
FREQUENCY AND PHASE REFERENCE setting in the SETTINGS ÖØ SYSTEM SETUP ÖØ POWER SYSTEM menu. Refer to the
Power System section of chapter 5 for additional details.
