Power Quality Analyzer Model 3945-B 41 The measurement type is selected using one of the six variable function but-tons. All of these measurements are valid in 3U, 3V, 3A, L1, L2 and L3. The waveforms are selected by pressing the buttons:- 3U displays the three phase-phase voltages of a three-phase system- 3V displays the three voltages of a three-phase system- 3A displays the three phase currents of a three phase-3 wire systemThe neutral current is not a direct measurement, but the resulting total of the3 currents measured.- L1, L2 or L3 displays the current and voltage, on phase one, two or three,respectively.IMPORTANT NOTE: The choice of waveforms to be displayed, in any dis-play mode, depends on the type of connection (see § 4.1.5).• Single-phase: No choice (L1) • Three phase-3 wire: 3U, 3V, 3A, L1, L2, L3• Two-phase: 2V, 2A, L1, L2 • Three phase-4 wire: 3U, 3V, 4A, L1, L2, L35.1.2 RMS Voltage Measurement on 3 Phases300VRMS0-300 V1= +2783 V2= -144 V3= -147 >207.6 v 204.4 v 204.9 v1 2 33U3V3AL1L2L3THD CF maxmin07/25/0259.99Hz 10:26 100 %Figure 5-2
