5.8 Actual values: FREQUENCY
Frequency
Frequency= 0.00 Hz
df/dt = 0.00 Hz/s
System Frequency value (Hz) and Frequency Variation (df/dt).
The VFR calculates frequency from voltage input
terminal 32-33
(A-B Line
voltage).
In case the metering of the line voltage cannot be done accurately, the frequency,
df/dt and frequency protection will be disabled.
