6.3.4 FREQUENCY
PATH: ACTUAL VALUES Ö A2 METERING ÖØ FREQ
Frequency is measured with a zero-crossing detector from the V
a
voltage. This measured frequency is used for Frequency
Tracking (see page 2–3 for details). Both of these values will read zero if the potential across the V
a
input terminals is less
than 10 V. When the FREQ DECAY RATE is positive, the frequency is increasing; when it is negative, the frequency is
decreasing.
6.3.5 SYNCHRONIZING VOLTAGE
PATH: ACTUAL VALUES ÖØ A2 METERING ÖØ SYNCHRO VOLTAGE
The voltage magnitude, phase angle, frequency, and delta values for the line VT synchronizing voltage input are displayed
as shown above. The
SYNCHRO FREQ value displays the measured frequency of the line VT input; it will be zero if the poten-
tial across the line VT input terminals is less than 10.0 V. The SYNCHRO DELTA value displays the differences of phase posi-
tion, voltage magnitude, and frequency between the line VT input and its corresponding bus VT input.
