63230-507-201A1 Power Meter 750

03/2007 Section 4—Metering

SECTION 4— METERING

METERING CAPABILITIES

POWER METER CHARACTERISTICS 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– 1 lists metering characteristics of the PM750.
