Real-Time Readings

The power meter measures currents and voltages, and reports in real time the rms values for all three phases and neutral. In addition, the power meter calculates power factor, real power, reactive power, and more.

Table 4–1lists some of the real-time readings that are updated every second along with their reportable ranges.
