The Arbiter Systems®, Inc. Model 929A Three Phase Power Meter is an economical alternative to both the Model 931A Power System Analyzer and the Model 930A Three Phase Power Analyzer when serial communication, dc voltage measurement, transducer calibration and timer features are not required
- Same high accuracy as Models 931A and 930A
- Features PowerDSA™ Digital Signal Analysis
- Complete diagnostic functions for use in substation and industrial power environments
- Field ready
- Multiple display options including three phase displays
- Basic three-phase display – Voltage, current, phase, frequency and power quantities on one convenient display.
The Model 929A has the same ac accuracy as the Model 931A with PowerDSA™ Digital Signal Analysis, and is a complete diagnostic tool for use in the substation and industrial power environment.
Model 929A measures all of the basic quantities: true-rms voltage and current, frequency and phase angle, as well as power quantities such as watts (W), watthours (Wh), volt-amperes (VA), volt-ampere hours (VAh), volt-amperes reactive (VAR), volt-amperes reactive hours (VARh), and power factor (PF), all with 0.11 % basic accuracy.
Measure harmonics and view the results graphically on the high contrast 240×64 graphic display. The two channels are normalized to Channel 1 fundamental phase, so you can see, for example, the relationship between current waveform distortions and voltage phase.
Vector display – view voltages, currents and phase angles with their vector representation.
Voltage/Current Sequence display – view voltage, current and phase along with positive, negative and zero sequence values.
Energy display – view voltage, current, phase, frequency and energy quantities on one convenient display.
