frequency, phase angle

U1-U1

Figure 8. Time measurement

The phase angle between voltage and current is determined by the times
between zero passage of the phase voltage U1 and those of the phase

currents I1, I2 and I3.

For further processing of the individual signal the signal processor
generates mean values over one second, which the following

microprocessor scans at intervals of one second.
